SATHEE: Gravitation Question 267

Gravitation Question 267

Question: Potential energy of a satellite having mass ?m? and rotating at a height of $[6.4 \times 10^{6} m]$ from the earth surface is [AIIMS 2000; CBSE PMT 2001; BHU 2001]

Options:

A) $[- 0.5, m g R_{e}]$

B) $[- m g R_{e}]$

C) $[- 2, m g R_{e}]$

D) $[4, m g R_{e}]$

Show Answer

Answer:

Correct Answer: A

Solution:

Potential energy = $[\frac{- G M m}{r} = \frac{G M m}{R_{e} + h} = \frac{- G M m}{2 R_{e}}]$ = $[- \frac{g R_{e}^{2} m}{2 R_{e}}]$ $[= - \frac{1}{2} m g R_{e}]$ $[= - 0.5 m g R_{e}]$
