URGENT, PLEASE SOLVE ASAP: Consider a black hole with a mass of 1.989×10^31kg. A 419,000 kg spaceship is orbiting this black hole at a distance of 1000.0 kilometers from its center. Assume the black hole is non-rotating (Schwarzschild black hole) Take the speed of light as 3 x 10^8 m/s.

A. Calculate the gravitational force acting on the spaceship.

B. The orbital velocity required to maintain this orbit.

C. The time dilation experienced by an observer on the spaceship compared to an observer from the edge of the black hole.
