1. A capacitor has a potential of 300J/C on the negative plate and 700J/C on the positive plate. A small sphere with a mass of 2.5 g and a charge of +0.0031 C enters the capacitor at the negative plate (through a small hole) with a velocity of 35 m/s towards the positive plate.

What is the potential half way between the plates? (If you are not sure, set it equal to some value and use that value in the next part.)

What is the velocity of the sphere when it is halfway between the plates?
