Answer:
Equation 1: R = (2GM) / (c^2) Equation 2: R = (2GM) / (3 x 10^8)^2 To verify Equation 2 using c= 3 x 10^8 m/sec, we substitute c with its value in Equation 1: R = (2GM) / ((3 x 10^8)^2) Simplifying the equation, we get: R = (2GM) / (9 x 10^16) Therefore, Equation 2 is verified using c= 3 x 10^8 m/sec for the speed of light.
