To get a better idea about tidal forces, Esperanza and Mikaassume that the black hole is about one solar mass, 2.0 ✕1030 kg, and that the distance from its center to theperson's feet is 3 km (the approximate Schwarzschild radius, thedistance at which the escape speed from the body becomesc, the speed of light). They also assume that the person'smass is 60 kg and the person's height is 2 m. How can they use theequation for the tidal force, Â
Ftidal = GMm (1/d^2 - 1/ (d+h)^2) to find how manytimes greater this tidal force is than the weight of the person onEarth, approximately 600 N? (Choose the ratio of the tidal force tothe weight of the person on Earth.)
