Hey Swapnil....
>> When work is said to be done??
Ans = When a force acts upon an object to cause a displacement of the object, it is said that work was done.
>> When work done on an object is zero??
Ans = When a force is exerted on an object which does not move,no work is done on the object.
>> Give one Example where work done on an object is zero.
Ans = (1) The work done against gravity in moving a book horizontally on a table is zero.
(2) If we try to move a heavy box, and the box is not at all moving, then the work done by us will be zero.
