A projectile is fired from the surface of the earth with a velocity of $5\text{m/s}$ and angle $\theta$ with the horizontal. Another projectile fired from another planet with a velocity of $3\text{m/s}$ 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 $g=9.8{\text{m/s}}^2$)

1. A
   $3.5$
2. B
   $5.9$
3. C
   $16.3$
4. D
   $110.8$
