Electric Insulator

An electron is accelerated from rest through a potential difference of 1800 V. What is its speed?

Points A and B are in a region of uniform electric field, $\vec{E}$ = < 65, 0 > N/C. Point A is at < -0.1, 0 > and Point B is at < 0.7, 0 >. Find the electron potential difference between point A and B.

Points A and B are in a region of uniform electric field, $\vec{E}$ = < -85, 25 > N/C. Point A is at < -0.5, 0 > and Point B is at < 0.7, 0 >. Find the electron potential difference between point A and B.

A circuit has 3 capacitors in series, A = 5 $\mu$F, B = 10 $\mu$F, C = 20 $\mu$F, with a 10 V battery. Find the potential difference across each individual capacitor.
