A bucket tied to a string is lowered at a constant acceleration of `g//4`. If mass of the bucket is m and it is lowered by a distance /then find then work done by the string on the bucket.

A bucket tied to a string is lowered at a constant acceleration of g//4 . If mass of the bucket is m and it is lowered by a distance l then find the work done by the string on the bucket.

A bucket of mass 'm' tied to a light rope is lowered at a constant acceleration of g//4 . IF the bucket is lowered by a distance 'd' , the work done by the rope will be (neglect the mass of the rope)

A bucket of mass 4//3 is tied to a string and is lowered at a constant acceleration of g//4 . The magnitude of work done (in joule ) by the string in lowering the bucket by 10 cm would be :

A block of mass m tied to a string is lowered by a distance d, at a constant acceleration of g//3 . The work done by the string is

A block of mass m tied to a string is lowered by a distance d, at a constant acceleration of g//3 . The work done by the string is

A block of mass m tied to a string is lowered by a distance d, at a constant acceleration of g//3 . The work done by the string is

A block of mass m tied to a string is lowered by a distance d, at a constant acceleration of g//3 . The work done by the string is

A boy tried to lift a bucketful of water , but failed. What is the work done by him ?

A man pulls out a block of mass m from the depth d with help of a light string. If acceleration of the block is g/2 then the work done by the string on the block will be
