Questions
An object is taken from a point P to another point Q in a gravitational field:
detailed solution
Correct option is Æ
Work done is independent of the path chosen and depends only on the initial and final positions of the object. Also the work done on any closed path in a gravitational field will be zero. Since, every point on the surface of the earth is at the same potential, no work is done for points on the surface of the earth. Hence, the correct choices are (a), (c) and (d).Talk to our academic expert!
