Q. 5. A mass of is at a point on a table. It is moved to a point . If the line joining and is horizontal,what is the work done on the object by the gravitational force? Explain your answer
The displacement of the object is horizontally on the table. We know that the gravitational force is acting in a downward direction. There is no displacement vertically.
Thus the work done by the gravitational force is zero.
