SATHEE: Gravitation Question 210

Gravitation Question 210

Question: Two satellite are revolving around the earth with velocities $[v_{1}]$ and $[v_{2}]$ and in radii $[r_{1}]$ and $[r_{2} (r_{1} > r_{2})]$ respectively. Then [BHU 2005]

Options:

A) $[v_{1} = v_{2}]$

B) $[v_{1} > v_{2}]$

C) $[v_{1} < v_{2}]$

D) $[\frac{v_{1}}{r_{1}} = \frac{v_{2}}{r_{2}}]$

Show Answer

Answer:

Correct Answer: C

Solution:

$[v = \sqrt{\frac{G M}{R}}]$

if $[r_{1} > r_{2}]$ then $[v_{1} < v_{2}]$
