Question

If you are 1.75m tall, what is the difference in gravity between your feet and your head when you are 4000 km from a 10 solar mass black hole? (1Mo = 2 x 10^(30) kg)

Answer 1

I believe the equation is:

dg =( -2GM / (r^3) ) * dr

Answer 2

i think the formula will b\[g=\frac{ GM }{ (R+h)^{2} }\]
