Taking the mass of the moon to be `7.3 xx 10^(22)` kg and the radius to be 1740 km calculate the acceleration due to gravity `'g_m'` on the surface of the moon. Compare it with the acceleration due to gravity `'g_e'` on the earth.

Text Solution

Verified by Experts

The correct Answer is:
`g_(m)=1.608 ms^(-2), g_(m)=(1/6)g_C`
