A point charge Q is located a short distance from a charged solid sphere with total charge 4Q and no other charges are present. If the force on Q is F, what is the magnitude of the force on 4Q?

three point charge are arranged on a line charge q3=+5.00nc and is at the origin charge q2=-2.00nc and is at x=+3.50cm charge q1 is at x=2.00cm.what is q1(magnitude and sign)if the net force on q3 is zero.

A positive point charge Q is located at x-a and a negative point charge -Q is at x = -a. A positive charge q can be placed anywhere on the y-axis. Find an expression for (FX, the x -component of the net force on q. Give your answer in terms of Q, q, a, y and constant K. Do your assessment by looking at (F)x when y = 0. net net

Pee charges are arranged in a triangle. The first charge has a magnitude of 9.6 nC and is located at the origin. The second charge is at the point (1.9 cm, 0) and has a magnitude of -3.1 nC. The third charge is at point (-0.5 cm, 1 cm) and has a charge of 12 nC. What is the magnitude of the total force on the third charge from the other two charges? Answer in microNewtons. Type your answer...

The figure below shows three charged particles at the cormers of an equilateral triangle. Particle A has a charge of 1.65 uC; 8 has a charge of 5.70 pC; and C has a charge of 5.04 uC. Each side of the triangle is 0.500 m long. What are the magnitude and direction of the net electric force on A? (Enter the magnitude in N and the direction in degrees below the +-axis.) 0.500 m 60.0 magnitude direction below the +X-axis

A positively charged particle Q1 = +25 nC is held fixed at the origin. A second charge Q2 of mass m = 9.5 μg is floating a distance d = 45 cm above charge Q1. The net force on Q2 is equal to zero. You may assume this system is close to the surface of the Earth.  Calculate the magnitude of Q2 in units of nanocoulombs.

A 0.01294 kg ball with a positive charge of 47.4 μC hangs from a light string right next to a large vertical metal plate (the metal plate is so large compared to the length of the string and ball consider it to be infinite in size).  How much surface charge density must the plate have to repel the ball so that the string makes and angle of 5.03 degrees from the vertical.  Give your answer to 3 significant figures and in units of nC/m/m (nanoCoulombs per meter squared: Blackboard has trouble with squred units).  Type in the units right after your numerical answer.

A charge +q is located at the origin, while an identical charge is located on the x axis at x = +0.74 m. A third charge of +2q is located on the x axis at such a place that the net electrostatic force on the charge at the origin doubles, its direction remaining unchanged. Where should the third charge be located?

The three point charges lie along the x-axis as shown in Figure. A positive charge of q1 = 2µC lies at x = 2.00 m, a positive charge of 92=6 uc lies at the origin, and the net force acting on 93 is zero. Where is the . x-axis position of 93? y 92 Answer x = 2.00 m 2.00-x F23 93 F13 91 x It's m.

A negatively charged particle with q= -1 μC is placed at the center of the uniformly charged cube with side a=1 mm and total charge Q= 3 C spread out over all six faces of cube. What is the total force acting on the particle in the center? Find the magnitude and direction.
