**1. Homework Statement**

In a simple model of the hydrogen atom, the electron moves in a circular orbit of radius 0.053 nm around a stationary proton. How many revolutions per second does the electron make?

**2. Homework Equations**

F = (kq1q2)/r^2 = (mv^2)/r

v = wr

**3. The Attempt at a Solution**

Charge of electron = -1.602 x 10^-19 C

Charge of proton = 1.602 x 10^-19 C

Mass of electron = 9.109 x 10^-31 kg

[(8.999 x 10^9)(1.602 x 10^-19)(1.602 x 10^-19)] / (0.053 x 10^-9) = (mv^2)/r

v = 0.002187 m/s

v = wr

0.002187 = w(0.053 x 10^-9)

w = 41267720.67

Any ideas on what I am doing wrong? Thanks!
