Let V and E denote the gravitational potential and gravitational field respectively at a point due to certain uniform mass distribution described in four different situations of column-I. Assume the gravitational potential at infinity to be zero. The value of and are given in column-II. Match the statement in column-I with results in column-II.

Options
- AA-(Q, R); B-(S, R); C-(P, R); D-(P, R)
- BA-(S, R); B-(P, R); C-(Q, R); D-(Q, R)
- CA-(P, R); B-(P, R); C-(Q, R); D-(P, R)
- DA-(R, Q); B-(Q, S); C-(S, R); D-(Q, S)
Correct answer
B. A-(S, R); B-(P, R); C-(Q, R); D-(Q, R)
Step-by-step solution
i. At centre of thin spherical shell,.
(V \neq 0, E=0)
ii. At centre of solid sphere, (V \neq 0, E=0).
iii. At centre of spherical cavity inside solid sphere, (V \neq 0, E \neq 0)
iv. At centre of two point masses.
(V \neq 0, E=0)
