Calculate the work required to move a planet’s satellite of mass 571 kg from a circular orbit of radius 2r to one of radius 3r, where 8.8 × 106 m is the radius of the planet. the mass of the planet is 7.76 × 1024 kg. answer in units of j]

5.6 x 10^9 J

Explanation:

mass of satellite, m = 571 kg

r1 = 2 R

r2 = 3R

R = 8.8 x 10^6 m

mass of planet, M = 7.76 x 10^24 kg

The formula for the work done is given by

Where, G is universal gravitational constant, G = 6.67 x 10^-11 Nm^2/kg^2

W = 5.6 x 10^9 J

would be false hope this out

that would be because of both gravity and friction. so     c
