Question

2 identical satellites s1 and s2 revolve around the Earth in circular orbits at distance R and 3R respectively from the surface of the Earth,

where R is the radius of the Earth. The ratio of linear momenta of s2 to s1 is.

Answer 1

so here mass for both is same
so v1 be velocity of s1
so v1= √2gme/√R
and v2= √2gme/3R
as linear momentum = mv
then find ratio

Answer 2

L = mvr

L=r

L1/L2=r1/r2

r1 = R+R=2R

r2 = 3R+R=4R

L1/L2=1:2
