When is workdone by force is zero?
work done on an object zero by a force would be zero isif the displacement of the object is zero
Is it possible workdone is zero although body is moving?
Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.Yes, if no force is applied. Work = force x distance, so if the force is zero, no work is done.
Why torque produce by centripetal force is zero?
because angle between r n F is zero, both r parallel.
Why work done by centripetal force during half rotation is zero?
work done is zero because force is toward the centre and distance is tangent to the circle so cos90 is equal to zero.[abbasia]
Is centripetal force a outward force?
No; "centripetal" implies an inward force.
What is the workdone by central force?
zero

Is Work done by centripetal force is zero?
An object moves in a circle at constant speed. The work done by the centripetal force is zero because: 1. the displacement for each revolution is zero 2. the average force for each revolution is zero 3. there is no friction 4. the magnitude of the acceleration is zero 5. the centripetal force is perpendicular to the velocity

Centrifugal force is reactionary force of centripetal force?
Yes true. But they need not be got cancelled though their resultant is zero.

How centripetal force equals to gravitational force?
The centripetal force is equal to the gravitational force when a particular body is in a circle. For a body that is in an orbit, the gravitational force is equivalent to the centripetal force.
Can centripetal force produce rotation?
no, but rotation can produce centripetal force
When is work done though displacement is zero?
When an object is propelled by a non-centripetal force through a closed path.
