for (a) would you just use Va-Vb= E* dl to find the potential difference?

Homework Statement Two test charges are brought separately into the vicinity of charge +Q. First the test charge +q is brought to a point A, a distance r from +Q. Next, +q is removed and a test charge +3q is broguht to a point B, a distance 2r from +Q. Compared with the electric potential...

There is just a picture with two lines representing the two parallel plates, the first line is labeled 10V and the second line is labeled 0V. There is a small circle in front of the 10V line with an arrow pointing to the right. That is all the information that is provided on the practice test.

Homework Statement A proton (q=+e, m= 1.67*10^-27 kg) traveling at 300 m/s enters a uniform electric region opposite to the field direction. a.) find the change in the energy of the proton as it moves 2 m across a potential difference of 100kV in this field. Express answer in eV. b)...

Homework Statement An electron (m= 9.1*10^-31 kg, q=-1.6*10^-19C) moving with a speed of 10^6 m/s enters the region between two parallel and oppositely charged metal plates across which the potential difference is 10V. Will the electron hit the opposite plate- show calculations on how you...
