Assume that the acceleration due to gravity on the surface of the moon is `0.2` times the acceleration due to gravity on the surface of the earth. If `R_e` is the maximum range of a projectile on the earth's surface, what is the maximum range on the surface of the moon for the same velocity of projection

Options

A. `0.2R_e`
B. `2R_e`
C. `0.5R_e`
D. `5R_e`

Answer

D

Explanation

`R_(max)=(u^2)/g,(R_e)/(R_m)=(g_m)/(g_e)=(0.2g)/grArr(Rmax)_m=5R_e`
