What Is the Schwarzschild Radius of a 100 Million-Solar-Mass Black $\frac{2 \mathrm{GM}}{\mathrm{c}^{2}}$

Multiple Choice

What is the Schwarzschild radius of a 100 million-solar-mass black hole? The mass of the Sun is about 2 × 10³⁰ kg,and the formula for the Schwarzschild radius of a black hole of mass M is:Rs = $\frac{2 \mathrm{GM}}{\mathrm{c}^{2}}$ (G = 6.67 × 10-11 $\frac{\mathrm{m}^{3}}{\mathrm{~kg} \cdot \mathrm{s}^{2}}$ ;c= 3 × 10⁸ m/s)

A) 3 km
B) 30 km
C) 3,000 km
D) 300 million km
E) 3 million km
