Question

An object is weightless inside a uniform spherical shell.

(a) True

(b) False

The question was posed to me during an interview for a job.

This intriguing question comes from Gravitation in section Gravitation of Physics – Class 11

Answer 1

Correct option is (a) True

Explanation: The net acceleration due to gravity is zero at all points inside a uniform spherical shell because of which an object is weightless. This is because the sum of gravitational force vectors from all sides of the object is zero inside the shell.
