Per NCERT §7.10 eqn 7.41, the potential energy of an orbiting satellite at distance (R+h) is which?
A+ G M m / (R + h)
B− G M m / (R + h)
C− G M m / [2 (R + h)]
D+ G M m / [2 (R + h)]
Answer & Solution
Correct answer: B. − G M m / (R + h)
NCERT eqn 7.41: PE = -GMm/(R+h) (V(∞) = 0). Negative because gravity is attractive.
