A sphere carries a charge of +2 nC. Point A is X = 0.02 m to the direct right of the sphere, and point B is Y = 0.06 m to the right of the sphere. Find the electrostatic potential difference from A to B. (the solution involves calculus)
A very long thin wire carries a line charge density, ##\lambda## = 361.0 ##\frac{nC}{m}##.

(this problem requires calculus)
The figure below shows two capacitors. The capacitor on the left has a uniform electric field, ##\vec{E}_1## = < 535, 0 > N/C. The capacitor on the right has a uniform electric field, ##\vec{E}_2## = < -225, 0 > N/C. If we define the point directly between A and B to be the origin, then point A is at < -0.4 , 0 > and point B is at < 0.4, 0 >. Find the potential drop on the path from A to B. If a proton traveled from rest at point A to point B, what would be its kinetic energy at point B?
