A stationary object is released from a point Pa distance 3R from the center of the moon which has radius R and mass M. Which one of the following expressions gives the speed of the object on hitting the moon?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
According to the law of conservation of energy,
Where m is the mass of the object, vq and vi are the initial and final velocities of object, respectively.
The object is stationary i.e., v 0 = 0.
