What is the distance of the circular path whose radius is 2R?

The circumference of the circle of radius r would be equal to 2πr. Thus, the circumference of the circle of radius 2R would be equal to 2π2R ⇒ 4πR. So, the total distance would be equal to 2 x 4πR ⇒ 8πR.

What are distance and displacement covered by a body in 1 round of a circle of RAD 7 cm?

Hence, The Distance Covered by body is 110cm. So, Displacement = 2r = 2 × 7 = 14m. Hence, The Displacement covered by is 14m.

When an object is moving in a circular path of radius R and completes a revolution then its displacement is?

Displacement will be 2R that is the length of the diameter.

When an object moves in a circle what will be it’s displacement after one complete rotation?

The distance covered in one complete rotation is equal to 31.4 cm and the displacement is equal to zero. Explanation: the displacement is the shortest distance between the starting and ending point.

What is the distance of a circle?

circumference
The distance around the boundary of a circle is called the circumference. The distance across a circle through the centre is called the diameter. The distance from the centre of a circle to any point on the boundary is called the radius. The radius is half of the diameter; 2r=d 2 r = d .

What is the displacement of the body after two rounds?

As the circle is of radius 2R so the body after two rounds will cover distance equal to: This is according to the formula: 2πr (where r is radius of a circle). Now for displacement we know that this is a vector quantity and we need to observe the initial and final position of the body.

What is the ratio of a body’s displacement to distance?

A body is moving along the circumference of a circle of radius R and completes half of the revolution. Then, the ratio of its displacement to distance is: Displacement is the minimum distance between the start and end point. Hence, the displacement in this case will be the diameter of the circle, i.e., 2R.

What is the distance of a circle with radius and displacement?

Distance will be quarter of circumference of a circle. So it is (2*pi*r)/4 which equals (pi*r)/2. Displacement is the shortest distance. Connecting center and two arc points, it will form a Right angled triangle with radius on two sides and displacement on third side.

How many times does a body complete a circle in 20 seconds?

A body completes one round of a circle of radius R in 20 seconds. What is the displacement of the body after 45 seconds?
