A projectile is fired from the surface of the earth with a velocity of \( 5 \mathrm{~ms}^{-1} \) at an angle \( \theta \) with the horizontal. Another projectile fired from another planet with a velocity of \( 3 \mathrm{~ms}^{-1} \) at the same angle, follows a trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is (in \( \mathrm{ms}^{-2} \) ) is ( given, \( g=9.8 \mathrm{~ms}^{-2} \) )
(a) \( 3.5 \)
(b) \( 5.9 \)
(c) \( 16.3 \)
(d) \( 110.8 \)
