Question
A particle of mass M is at a distance a from surface of a thin spherical shell of equal mass and having radius a.
- Gravitational field and potential both are zero at centre of the shell.
- Gravitational field is zero not only inside the shell but at a point outside the shell also.
- Inside the shell, gravitational field alone is zero.
- Neither gravitational field nor gravitational potential is zero inside the shell.
The correct answer is: Neither gravitational field nor gravitational potential is zero inside the shell.
