Alarge asteroid of mass 98700 kg is at rest far away from any planets or stars. a much smaller asteroid, of mass 780 kg, is in a circular orbit about the first at a distance of 201 meters as a result of their mutual gravitational attraction. what is the speed of the second asteroid?

1.81 x 10^-4 m/s

Explanation:

M = 98700 kg

m = 780 kg

d = 201 m

Let the speed of second asteroid is v.

The gravitational force between the two asteroids is balanced by the centripetal force on the second asteroid.

Where, G be the universal gravitational constant.

G = 6.67 x 10^-11 Nm^2/kg^2

v = 1.81 x 10^-4 m/s
