Question

How close would two stationary electrons have to be positionedso that their total mass is 5 times whatit is when the electrons are very far apart? This is my version of the question, and im not sure where toplace the 5 into the equation.

Explanation / Answer

Given : Mass of the each electron ( m ) = 9.1 *10-31 kg Total mass of the two electrons  mtot = ( m1 + m2 ) = 2 ( 9.1 * 10-31 kg) = 18.2 * 10-31 kg total mass is 5 times      mtot = 5 (18.2*10-31 kg ) = 91 * 10-31 kg = 9.1 *10-30 kg rn =oh2/Ze2 [ for H]    Solve it I hope it helps you
