A point mass \( m \) is placed inside a spherical shell of
P
radius \( \mathrm{R} \) and mass \( \mathrm{M} \) at a distance \( \frac{R}{2} \) from the centre
W.
of the shell. The gravitational force exerted by the shell on the point mass is
(1) \( \frac{G M m}{R^{2}} \)
(2) \( \frac{2 G M m}{R^{2}} \)
(3) Zero
(4) \( \frac{4 G M m}{R^{2}} \)
