Homework Help: Fields and Schwartzchild radius for a black hole

  1. Jun 24, 2012 #1
    1. The problem statement, all variables and given/known data
    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?

    2. Relevant equations
    V^2 = GMe/Re

    3. The attempt at a solution
    I tried using the above equation to find the M, but that was not the right answer...

    Your formula is incorrect, V2 = (2GM)/r.

    And then I solve for m?
