Inside ShellMediumQuestion 30714
Question
Gravitational field INSIDE a uniform hollow spherical shell is:
- AEqual to g at the surface
- BStronger near the inner surface
- CZero everywhere insideCorrect
- DProportional to distance from centre
Correct answer
Zero everywhere inside
Explanation
By the shell theorem, a uniform hollow shell exerts zero net gravitational force on any mass placed inside it. The contributions from all parts of the shell cancel exactly.
