On average, an electron in a Hydrogen atom is about 5.3 x 10^-11 meters from the proton. The mass of an electron and proton are 9.1 x 10^-31 kg and 1.7 x 10^-27 kg respectively. The charge of each, positive for the proton and negative for the electron, is 1.6 x 10^-19 C.

1). What is the magnitude in Newtons of the electric force the proton exerts on the electron?

2). Is the force attractive or repulsive?

3). What is the magnitude in Newtons of the force the electron exerts on the proton?

4). What is the electrical potential energy in Joules of the electron (remember to include the appropriate sign)?

5). How much kinetic energy (in Joules) does the electron have to have in order for the system not to be a bound one?

6). If the electron is moving with a velocity of 2.2 x 10⁶ meters per second, how much energy in Joules do you have to add to it to free the electron from the proton's grip?
