Determine the magnitude of the force, in micronewtons, being experienced by a -9-nC charge at (9, -5, 8) due to three infinite sheet charges. One is -5 mC/m2 at x = -8, another is 7 mC/m2 at y = 6, while the last one is 5 mC/m2 at z = zC. All coordinates is measured in meters.

An electron flies into a constant electric field (along the direction of the lines of E-field). The initial electron velocity is 10 km/s. Calculate the magnitude the electric field if the electron stops in 6 nsec. The electron mass is me =9.11×10-31 kg, the electron charge is qe = -1.61×10-19 C.

A point charge q1 = +5.00 μCoul is held in fixed space. From a horizontal distance of 6.00 cm, a small sphere with mass 4.00*10^-3 kg and charge q2 = +2.00 μCoul is fired toward the fixed charge with an initial speed of 50.0 m/s. Gravity can be neglected. What is the distance between the two charges when the speed of the moving charge q2 is 20.0 m/s?

Two 1.5-cm-diameter disks face each other, 1.5 mm apart. They are charged to ± 10 nC .     A proton is shot from the negative disk toward the positive disk. What launch speed must the proton have to just barely reach the positive disk? Express your answer in meters per second.     I thought the anwser was 1.1*106  but this was incorrect

On a plastic disc of radius R = 10 cm, an electric charge per unit area has been distributed proportional to the distance to the center, the proportionality constant being c = 2 μC/m. Determine the total load of the disk:
