Write true or false for the following statements : In order to get minimum work, the angle between force and displacement should be 90.

Question

Philoid · Accepted Answer

True

Explanation: When force is applied at an angle to the direction of motion of object then the work in the direction of motion is given by: W = Fs cos θ

If angle θ between force and displacement is 90 then cos θ will be equal to zero.

So, work done will also be zero by the given formula which means minimum.

Write true or false for the following statements :In order to get minimum work, the angle between force and displacement should be 90.
