Question

Two satellites revolving around a planet in the same orbit have the ratio of their masses m₁/m₂ = 1/2. The ratio of their orbital velocities m₁/m₂ = ........... . (A) 1 (B) 1/2 (C) 2 (D) 4

Answer 1

Answer:

velocity not depends on mass

$v \: \alpha \: \frac{1}{ \sqrt{r} } \\ \\ so \: \: option \: \: (a) \: \: is \: \: correct$

Answer 2

Answer:

Option (A) IS CORRECT.

Explanation:

Since we know the expression for the orbital velocity,

$V_{o} =\sqrt{\dfrac{GM}{R+h} }$

Wher G = Gravitational constant, M=mas of the earth, R= Radius of the earth,h=altitude at which satellite placed.

Since both satellites are orbiting in the same plane so, h is also constant.

So, orbital velocity is the function of consatnts.

So,ratio of the orbiting velocity of the two satellite is 1:1.

So,option (A) IS CORRECT.
