Two satellites are revolving around earth. Orbital radius and orbital velocity of the one satellite is R1 AND V1 respectively. Find the orbital radius of other satellite whose orbital velocity is v2.

Please answer this.,

'V' is directly propotional to root of 'r'

Therefore, V1 / V2 = ROOT OF (R1 / R2) R2 = (R1*V12) / V22 (After squaring on both sides).Are you a Fitjee student ? Actually this question came in the Fitjee book, that's why .

Centripetal force = mv^2/r So v^2 is directly proportional to r So v1^2/v2^2= r1/r2 So r2 = r1* v2^2/v1^2

One correction... It will be v1^2/v2 ^2 = r2/r1 So r2 is r1*v1^2/ v2^2
