Question

Two satellites are orbiting around the earth in circular orbits of same radius. One of them is 10 times greater in mass than the other. Their period of revolutions are in the ratio ______.

विकल्प

• 100 : 1

• 1 : 100

• 10 : 1

• 1 : 1

Answer 1

Two satellites are orbiting around the earth in circular orbits of same radius. One of them is 10 times greater in mass than the other. Their period of revolutions are in the ratio 1 : 1.

Explanation:

v = `(2pi"R")/"T"`

or, T = `(2pi"R")/"v"`

∴ T is not dependent on mass

∴ If M₁ = 10M₂

T₁ : T₂ = 1 : 1
