A point charge of -6 x 10-9 C is 3 m from point A and 5 m from point B. (a) Find the potential at point A. (b) Find the potential at point B. (C) How much work is done by the electric field in moving a 2 nC particle from point A to point B? (type your answer in scientific notation.)

Three point charges are placed on the x-axis.  30 µC at the origin, -56 µC at x=0.292 m, -85 µC at x = 0.96 m. Find the magnitude and direction of the net force acting on -56 µC charge. What is the electric potential at (0, 0.96m)? What is the  electric field at (0, 0.96m)?

Two identical charges q = (1/9.0) x 10-9 C are shown in the figure below. Find the potential at P. (Take r = 2.28 m and 0 = 41°.)

How much work does an electric field do when moving a +450µF charge from ground to a point where the potential is +100V higher?     -0.01J     0.045J     0.01J     -0.045J

How much work does the electric field do in moving a +7.2 µC charge from ground (0 V)to a point where the potential is +58V higher? Pay attention to magnitude and sign.

The three charges in the figure below are at the vertices of an Isosceles triangle. Let q = 5.50 nC and calculate the electric potential at the midpoint of the base. (Let d = 1.50 cm and d₂ = 8.00 cm.) d₁ d₂ X Enter a number. differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully kV Need Help? Read it
