Find the acceleration due to gravity of the moon at a point 1000 km above the moon's surface. The mass of the moon is `7.4xx10^2` kg and its radius is 1740 km.

Text Solution

Verified by Experts

The correct Answer is:
B
`(GM)/((R+h)^2)=(6.67xx10^-11xx7.4xx10^22)/((1740+10000)62xx10^6)`
`=(6.67xx7.4xx10^11)/(2740xx2740xx1066)`
`=0.65 m/s^2`
