Can the resultant of three forces be zero?

The following sets of three vectors act on a body. Following sets of three forces act on a body. Whose resultant can not be zero.

Under what conditions will the resultant of three unequal forces be zero?

(i) When three vectors are not lying in one plance, they can bot produce zero resultant. (ii) When three vectors are lying in a place and are represented in magnitude and direction by the three sides of a triangle taken in the same order, they can prokuce zero resultant.

Can 3 equal magnitude vectors add to zero?

Yes, it is possible to add three vectors of equal magnitudes and get zero. and A , → B → and C → ,given these three vectors make an angle of with each other. Consider the figure below: Lets examine the components of the three vectors.

Can three unequal vectors add up to the zero vector if so under what conditions?

Since a scalene triangle exists, three unequal vectors can add up to zero. The conditions for three vectors to form a triangle are: The sum of magnitudes of any two of them must be greater than the magnitude of third. magnitude of sum of two vectors must be equal to the magnitude of third.

Can the resultant of two unequal forces be equal to zero?

Yes if both forces applied are equal and are in opposite direction. If two unequal forces are exerted on a box the net force could never be zero. It is graphically impossible to take twodirected line segments (vectors) of unequal length and place them tail to tip and end up with a resultant of zero.

Which group of forces can give zero resultant?

– The resultant forces may also become zero when the sum of forces in one direction is exactly opposed by the force of the same magnitude in opposite direction. for eg 10+10 in one direction and 20 in opposite direction.

Can the resultant of two unequal forces equal to zero?

If two unequal forces are exerted on a box the net force could never be zero. It is graphically impossible to take twodirected line segments (vectors) of unequal length and place them tail to tip and end up with a resultant of zero. Similarly, you can not add two integers of unequal magnitude and end up with zero.

What is the minimum number of unequal forces whose resultant will be zero?

three vectors
From triangle law of vectors minimum three vectors are required to give zero resultant.

Can we combine three vectors of unequal magnitude to get a zero resultant How about three vectors of equal magnitude?

Is it possible to add three vectors of equal magnitudes and get zero? Answer: Two vectors of unequal magnitudes cannot be added to get zero. Three vectors of equal magnitudes can be added to get zero. Explanation: While adding two vectors we get minimum resultant value if their directions are opposite.

Can the vector sum of two unequal forces be zero?

No. The sum of two vectors can only be zero if they are in opposite directions and have the same magnitude.
