Two identical space probes, each of mass 2.00 x 10 4 kg are “parked” in outer space. If they are separated initially by 1.00 km, how long (in hours) will it take for the distance between them to decrease by 1.00 m, due to gravitational attraction? (Assume that the gravitational force remains constant as the probes move closer to each other.)

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
