Question:medium
There is a shell of mass \( M \) and density of the shell is uniform. The work done to take a point mass from point A to B is \( [AB = r] \)
There is a shell of mass \( M \) and density of the shell is uniform. The work done to take a point mass from point A to B is \( [AB = r] \)
Show Hint
For a spherical shell, the gravitational field inside the shell is zero, so no work is done to move an object within it.
