Question

2 satellites a and b ratio of masses 3 is to 1 in circular orbit of radius r and 4r then the ratio of total mechanical energy of a and b is

Answer 1

The ratio of total mechanical energy of a and b is 12:1

Explanation:

The formula of energy is given below:

Energy  E = -GMm / 2r

Ratio of mechanical energy.

E1 /E2  = m1 / r1 × r2 /m2

           = [ m1 / m2] [r2 / r1]

           =3 / 1 × 4 / 1 = 12 / 1

Thus the ratio of total mechanical energy of a and b is 12:1
