Question

A satellite of mass ‘m’, moving around the earth in a circular
orbit of radius R, has angular momentum L. The areal velocity
of satellite is (Mₑ = mass of earth)
(a) L /2m (b) L /m
(c) 2L /m (d) 2L /Mₑ

Answer 1

Answer:

According to kepler's second law, areal velocity is constant .

i.e. Av=rv/2=wr^2/2=L/2m

option (a)

L/2m

if there is any doubt then ask it
