PHYSICS 182 Lecture Notes - Lecture 12: Test Particle

the electrical potential at a certain point is space is 12 V. what is the electrical energy of a -3.0 uC charge place at that point?

Two point charges q1=+2.40x10^-9C and q2=-6.50x10^-9C at 100 metersapart. Assume electric potential is zero at infinity.

A) What is the electrical potential at point A
B) What is the electrical potential at point B?
C) What is the work done by the Electric Field on a charge of+2.50x10^-9 that travels from point B to point A?

1. What is the change in the electrical potential energy in a lighting bolt if 35C of charge travel to the ground from a cloud 2.0 km above the ground in the direction of the field? Assumer the electric field is uniform and has a magnitude of 1.0 x 10^6 N/c
