Question

# A body of mass 'm' is taken from the earth's surface to the height equal to twice the radius (R) of the earth. The change in potential energy of body will be -mg 2R23mgR3 mgR13mgR

A
13mgR
B
mg 2R
C
3 mgR
D
23mgR
Solution
Verified by Toppr

#### Mass = m, height = 2RAt height the acceleration due to gravity decreases , hence the value of acceleration due to gravity becomes g' = g1+h/R = gRh+RThe value of potential energy =mgh=mghRh+RNow h=2R (given)Henc change in potential energy = 23mgR
