Q. 84.0( 1 Vote )

Let V and E represent the gravitational potential and field at a distance r from the Centre of a uniform solid sphere. Consider the two statements:

(A)The plot of V against r is discontinuous

(B)The plot of E against r is discontinuous

A. Both A and B are correct.

B. A is correct but B is wrong.

C. B is correct but A is wrong.

D. Both A and B are Wrong.

Answer :

The graph of electric field versus distance and potential versus distance is shown in the figure below.

From the graph it is clear that the electric field has a discontinuity at a distance equal to the radius (r=R), while the potential is a continuous function.
