Satellite Energy & Weightlessness question from JEE Main 2016 (10 Apr, Shift 1 (one Or More Correct))

Answer: (b)

1. Weightlessness means no normal reaction, not zero gravity; gravity still supplies the centripetal force.
2. At distance $R + h$ from the centre: $F_G = \frac{GMm}{(R+h)^2}$.
3. Since $R + h > R$, this value is less than $\frac{GMm}{R^2}$ but greater than zero, so $0 < F_G < \frac{GMm}{R^2}$.
4. So the answer is (b) $0 < F_G < \frac{GMm}{R^2}$.
