What is the correct velocity of an electron in a bound orbit around a proton?

[QUOTE="LukasMont, post: 6015403, member: 647354"] Good evening! The question states: [B]9. Electron in bound orbit about proton. Suppose that an electron moves in a circular orbit about a proton at a distance of 2 X l0^-8 cm. Consider the proton to be at rest. (a) Solve for the velocity of the electron by equating the centrifugal and electrostatic forces. [/B] Considering that the elementary charge (charge of the electron is e = 4.8 x 10^-10 statcoloumbs), working on the cgs system, I equated the centrifugal force Fc=v²/r and the eletrostatic force Fe= e²/r². My way of solving the problem was: Fc=Fe, v²/r = e²/r² v²= e²/r v= (e²/r)¹/² v= (2.3x10^-19/2x10^-8)¹/² v = 11.5x10^-6 cm/s. Which is clearly a way down from the correct value. Could anyone please help me? Thanks! [/QUOTE]
