SATHEE: Gravitation Question 241

Gravitation Question 241

Question: Two satellites A and B go round a planet P in circular orbits having radii 4R and R respectively. If the speed of the satellite A is 3V, the speed of the satellite B will be. [MNR 1991; AIIMS 1995; UPSEAT 2000]

Options:

A) 12 V

B) 6 V

C) $[\frac{4}{3} V]$

D) $[\frac{3}{2} V]$

Show Answer

Answer:

Correct Answer: B

Solution:

$[v = \sqrt{\frac{G M}{R}}]$ Þ $[\frac{v_{A}}{v_{B}} = \sqrt{\frac{R_{B}}{R_{A}}} = \sqrt{\frac{R}{4 R}}]$ $[= \frac{1}{2}]$ $[\frac{v_{A}}{v_{B}} = \frac{3 V}{v_{B}} = \frac{1}{2}]$ $[∴,, v_{B} = 6, V]$
