A proton moving at 0.999 of the speed of light orbits a black hole 4972 km from the center of the attractor.What is the mass of the black hole? A)6.71 × 10³³ kg B)6.71 × 10³⁰ kg C)6.71 × 10³⁶ kg D)6.71 × 10²⁵ kg

Question

Quizplus · Accepted Answer

The correct answer is A because the mass of the black hole can be calculated using the formula M = (4/27) * (c^3 * r / G), where M is the mass of the black hole, c is the speed of light, r is the distance from the center of the attractor, and G is the gravitational constant. Plugging in the given values, we get M = (4/27) * (3 x 10^8 m/s)^3 * (4972 km * 1000 m/km) / (6.674 x 10^-11 m^3 kg^-1 s^-2) = 6.71 x 10^33 kg.
