When a body is whirled in a vertical circle at the end of the string tension in the string is maximum at?
It is maximum at the lowest point and minimum at the highest point. Hence the motion in vertical circle is not uniform circular motion. The Expression for Velocity of Body Moving in a Vertical Circle: Consider a small body of mass ‘m’ attached to one end of a string and whirled in a vertical circle of radius ‘r’.
When a stone tied to one end of a string is whirled in a vertical circle the tension in the string is the least at?
If a stone is tied to one end of the string and whirled in vertical circle, then the tension in the string at the lowest point is equal to. (A) centripetal force.
How do you find the tension at the top of a vertical circle?
Motion in a Vertical Circle
- For a mass moving in a vertical circle of radius r = m,
- For a velocity at the top vtop = m/s.
- the velocity at the bottom is vbottom = m/s.
- For a mass m = kg,
- the tension at the top of the circle is Ttop = Newtons.
- The corresponding tension at the bottom of the circle is Tbottom = Newtons.
When a stone is whirled by a string in a circular path in a horizontal plane no work is done explain why?
Work done by the stone is zero. Here, in circulation path displacement is zero. Also tangential velocity makes angle 90°.
When a body is whirled in a circle then the work done on it by the tension in the string is?
When the body is whirled in a circle, then the work done on it is told to be zero. This is because the centripetal force or the ma as we tell acts on the body towards the centre and perpendicular to the circular motion of the body.
What is a vertical circular motion?
A body revolves in vertical circle such that its motion at different points is different then the motion of the body is said to be vertical circular motion. consider an object of mass tied at one end of a mass m tied at one end of an int extensible string and whirled in a vertical radius of radius r.
When a particle is moved in a vertical circle?
it has constant radial and tangential acceleration. it has variable tangential and radial acceleration.
What is the net force acting on the stone at the bottom of a vertical circle?
T1 and v1 denote the tension and speed at the lowest point. T2 and v2 denote corresponding values at the highest point….
| Lowest Point | Highest Point | |
|---|---|---|
| b | mg + T1 | mg – T2 |
| c | mg + T1 – mv12/R | mg – T2 + mv12/R |
| d | mg – T1 – mv12/R | mg + T2 + mv12/R |
What is tension in circular motion?
Assuming the circular motion being carried by a string and a mass attached to one of its end then the tension on string can be equated to the centrifugal force. T=mv²/r. m= mass of object. v= velocity of the object (tangentially).
When a ball is whirled in a circle and the string supporting?
Yes the ball has an angular rotation about its center. If we notice the position of the point on the ball where it is tied with the string we can see that it is moving about its center as its position changes. This point again comes to the same position when the ball makes a complete revolution around the fixed point.
When a ball is whirled in a circle and the string supporting the ball is released the ball flies off tangentially?
If the string break , the stone flies away tangentially . Why? The velocity of the stone at any instant is along the tangent to the circle at that instant When the string breaks centripetal force whirling the stone vanishes Therefore on account of inertia the stone flies off tangentially .
How does a stone Whirl in a circle?
A stone tied to a string of length l is whirled in a vertical circle with the other end of the string at the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude in its velocity as it reaches a position, where the string is horizontal, is POPULAR CHAPTERS BY CLASS
What happens when a stone is tied to a string?
A stone tied to a string of length l is whirled in a vertical circle with the other end of the string at the centre. At a certain instant of time, the stone is at its lowest position and has a speed u. The magnitude in its velocity as it reaches a position, where the string is horizontal, is
What is the velocity of stone when string is horizontal?
Ans: Velocity of stone at the lowermost point = 7 m/s, Velocity of stone when string is horizontal = 5.42 m/s, Velocity of stone at topmost point = 3.13 m/s, Tension at lowermost point = 58.8 N, Tension when string is horizontal = 0 N, Tension at topmost point = 29.4 N
What is tension in motion of body in vertical circle?
This is an expression for the velocity of a particle at any point performing a circular motion in a vertical circle. The Expression for Tension in the String in Motion of Body in Vertical Circle: This is the expression for the tension in the string. Case – I: When the body is at the lowermost position i.e. body is at L) (h = 0)
