Physics · GRAVITATION
हिन्दीA point mass \( m \) is placed inside a thin, uniform hollow spherical shell of total mass \( M \) and radius \( R \) at a distance \( r = \frac{R}{3} \) from the centre. The gravitational force exerted on the point mass by the shell is:
Correct answer · Option 1
Zero
Explanation
According to Newton's shell theorem, the force of attraction due to a hollow spherical shell of uniform density on a point mass situated anywhere inside it is identically zero.
