what should be the angle between the direction of force and the direction of motion of a body so that work done is zero? |
|
Answer» Answer: Angle should be 90° between the DIRECTION of force and the direction of motion of a body as workdone is EQUAL to force . or F=Force ,d= Displacement ,theta =Angle between force and displacement W = F.D.costheta cos90° = 0 so,in case of zero WORK, the angle between the force and displacment is 90°. |
