Question

Two satellites of mass m₁ and m₂ (m₁ > m₂) are going around the earth in orbits of radius r₁ and r₂ (r₁ > r₂). Which statement about their velocities is correct?

(a) v₁ < v₂ 

(b) v₁ > v₂

(c) v₁/r₁ = v₂/r₂ 

(d) v₁ = v₂ 

Answer 1

Correct option (a) v₁ < v₂ 

Explanation :

For a satellite of mass m moving in an orbit of radius r,
