A spherical planet has a mass \( M_{P} \) and diameter \( D_{P} \). A particle of mass \( m \) falling freely near the surface of this planet will experience an acceleration due to gravity, equal to
[CBSE PMT (Pre.) 2012]
(a) \( 4 G M_{P} / D_{P}^{2} \)
(b) \( G M_{P} m / D_{P}^{2} \)
(c) \( G M_{P} / D_{P}^{2} \)
(d) \( 4 G M_{P} m / D_{P}^{2} \)
