What should be the angle between the direction of motion of a body so that the work done is zero ?

A Force F acts on a body and displaces it by a distance S in direction at an angle theta with the direction of force ,(a) Write the expression for the work done by the force,(b)What should be the angle between the force and displacement so that the work done is (i)zero ,(ii)Maximum ?

A force acts perpendicular to the direction of motion of a body. What is work done?

What should be the angel between the direction of force and displacement for maximum and minimum work?

What should be the angel between the direction of force and displacement for maximum and minimum work?

If the angle between force and displacement is obtuse, then the work done is

What should be the angle between the force and displacement for minimum and maximum work.

For what value theta is work done zero?

In given magnetic field , what should the direction of motion of the conductor so that the maximum induced current can be produced ?

The work done by a force acting obliquely is given by the formula : W = F cos theta xx s . What will happen to the work done if angle theta between the direction of force and motion of the body is increased gradually ? Will it increase, decrease or remain constant ?
