Black hole questions

[Random1201]

How many solar masses would a Black hole yield if it were the exact diameter of earth?

And what Attack Potency would one be granted for moving it at Massively Hypersonic speeds with telekinesis (specifically Mach 1690).

4,2935414593616606040023088455772 x 10^33 kg or 2158,5347440358255512554968807889 solar masses.

The KE would be 2,4888371777481738023220183685157 x 10^39 J

How was the value for the weight/solar masses obtained?

Schwarzschild radius formula.

R=(2*G*M)c^2) -> M=(R*c^2)2*G)

In this case, R is Earth's radius

Perfect

Minor thing, but don't remove threads, it makes harder for others who have the same question to find it. I can close it for you
