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

(a)  0.2${R}_{\epsilon }$                      (b) 2${R}_{\epsilon }$

(c)  0.5${R}_{\epsilon }$                      (d) 5${R}_{\epsilon }$
