a stationary object is released from a point P at a distance 3R from the centre of the moon which has radius R and mass M. Whiich of the following gives the speed of the object on hitting the moon?
1. (2GM/3R)^1/2
2. (4GM/3R)^1/2
3. (GM/3R)^1/2
4. (GM/R)^1/2

Dear Ashish, this is wrong way since the acceleration of the object is not uniform for such large distances.
Why cannot we use Acceleration = GM/9R^2 And use third equation of motion V^2 -u^2 = 2 a s Where s= 2R U=0 Answer do not match then
