A projectile is fired from the surface of the earth with a velocity of $5\ \text{m s}^{-1}$ and angle $\theta$ with the horizontal. Another projectile fired from another planet with a velocity of $3\ \text{m s}^{-1}$ at the same angle follows a trajectory which is identical with the trajectory of the projectile fired from the earth. The value of the acceleration due to gravity on the planet is (in $\text{m s}^{-2}$) (Given g = $9.8\ \text{m s}^{-2}$) 3.5 5.9 16.3 110.8
