Question

Two satellites p1 and p2 are revolving in orbit of radii R and 4R. The ratio of maximum to minimum angular velocities of line joining P1 and P2 is

Answer 1

Hey mate,

● Answer-
v(max)/v(min) = √4

● Explaination-
Gravitational force equalizes to centripetal force.
GMm/r^2 = mv^2/r
v = √(GM/r)

When r = R,
v1 = √(GM/R)

When r = 4R,
v2 = √(GM/4R)

Ratio of maximun to miniimum velocities is-
v1/v2 = √(GM/R) / √(GM/4R)
v1/v2 = √4

Hope this helps you...
