A homogeneous bar of lenght \( L \) and mass \( M \) is situated at a distance \( h \) from a particle of mass \( m \)
\( \mathrm{P} \) as shown. The gravitational force exerted by the

WV bar on the particle varies inversely as
(1) \( (\mathrm{h}+\mathrm{L} / 2)^{2} \)
(2) \( h(h+L) \)
(3) \( h^{2} \) if \( L \)
(4) Both (2) and (3)
