^{-11}m.

(a) What is the linear speed of the electron?

(b) What is the angular speed of the electron?

(c) How long does it take for the electron to complete one orbit?

I know how to solve for parts b and c, but do not know how to answer a, and thus can't solve the other two parts.

For part a, I have the the net force acting upon the electron is equal to mV

_{t}

^{2}/r. What exactly is the net force on the electron? Is it F

_{e}or F

_{g}or both?

I calculated F

_{e}earlier and attained a value of 0.00816 N.
