Gravitational Potential & Energy
Inside a uniform spherical shell:
(1) the gravitational field is zero
(2) the gravitational potential is zero
(3) the gravitational field is same everywhere
(4) the gravitational potential is same everywhere
(5) all of the above
Choose the most appropriate answer from the options given below:
Show answer and solution
Answer: (a)
- Inside a uniform shell the field is zero everywhere, so (1) and (3) are true.
- Zero field means the potential is constant, equal to ; so (4) is true.
- That potential is not zero, so (2) is false, and hence (5) is false.
- So the answer is (a) (1), (3) and (4) only.
