Fields and Schwartzchild radius for a black hole

[hybridized]

Homework Statement

The Schwartzchild radius for a black hole is the distance from the singularity of the black hole at which the escape velocity is the speed of light. You wish to create a black hole, with radius of only 1.0m for personal research. How much mass would this required? Would the mass of the earth, 6.0 x 10^24 kg do the job?

Homework Equations

V^2 = GMe/Re

The Attempt at a Solution

I tried using the above equation to find the M, but that was not the right answer...
