Question

what should be the angle between the direction of force and the direction of motion of a body so that the work done is zero​

Answer 1

Answer:

angle should be 90° between the direction of force and the direction of motion of a body as work done is equal to force multiplied by displacement multiplied by cosx. and here X=90° so cos90°= 0 so the overall work done will be zero.

Hope it helped.

Answer 2

the angle should be 90° degree
