A +1 nC charge is located at (0,10.16) cm and a -4nC charge is located (4.95, 0) cm.Where would a -2 nC charge need to be located in order that the electric field at the origin be zero? Find the distance r from the origin of the third charge.

A +7 nC charge is located 3.2 meters to the right of a +6 nC charge. Determine the magnitude of the electric field at the midpoint of the two charges. Express your answer as a positive number in N/C.

Two point charges lie along the y-axis. A charge of q1 = -8 ?C is at y = 6.0 m, and a charge of q2 = -7 ?C is at y = -4.0 m. Locate the point (other than infinity) at which the total electric field is zero.

Tthree point charges, Q1 = 18.4 µC, Q2 -33.6 μC, and Q3 = 87.3 μC are positioned at three corners of a square as shown in the figure. A fourth point charge is located at the open corner at point A with a charge of QA = 15.5 μC. The square has height y of 40.1 cm and width x of 40.1 cm.

Imagine you have four identical charge q, placed on the corners of a square. If q = 17.37 nC, then the side of the square is s = 7.2 cm, calculate the magnitude of the electric field acting on the charge at the upper right corner. NOTE: Final answer in SIX decimal places. Then, state the SI unit of the variable being sought off. Add your answer

The magnitude of the electric field is 75 N/C at a distance of 64 cm from a point charge. What is the magnitude of the charge, in coulombs.

Two charges — q1 = 2.3 × 10-6C, q2 = 5.6 × 10-6C — are separated by a distance of d = 4.75 m.    At what distance, r in meters, from the first charge is the electric field zero?

Problem 8:  The electric force experienced by a -4.8 μC charge at some point P has a magnitude of 18 N and points due North.  Part (a)  What is the magnitude of the electric field, in newtons per coulomb, at P?   Part (b)  What is the direction of the electric field at point P?  Part (c)  What is the magnitude of the force, in newtons, that an electron would experience if it were placed at point P instead of the given charged particle?  Part (d)  If a proton were placed at point P instead of the electron, what is the magnitude of the force, in newtons, that it would experience?  Part (e)  What is the ratio of the magnitude of the acceleration of an electron to that of a proton, when the electric field acting on each has the same strength?
