Two equal positive charges are placed equidistant on either side of another positive charge. What would the middle positive charge experience?

A point charge of +1.0 μC is held fixed at the origin. A second charge of -1.0 μC and mass 4.6 ×10−2kg is placed on the x axis and released. Where should the charge be placed so that its initial acceleration will be +1.0 m/s2 ? (Neglect gravity.) Express your answer with the appropriate units.

It is 15 km from downtown bozeman, Montana, to the Ridge, atop the Bridger bowl Ski area. If 1 C positive charge is placed on the top the ridge and a 1C positive charge is place atop the Baxter hotel in downtown Bozeman, what will be the force of repulsion between the two charges?

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.

Two charged particles of charges 3 μC and -2 μC are placed on the x-axis on x = -2 cm and x = 2 cm respectively.  Determine the magnitude and direction of the force acting on a -1 μC charge placed on the y-axis at the y = 1.5 cm position.

(a) Two point charges totaling 8.50 μC exert a repulsive force of 0.200 N on one another when separated by 0.479 m. What is the charge (in µC) on each? smallest charge 1.0 X UC x uc largest charge 8.39 (b) What is the charge (in uc) on each if the force is attractive? smallest charge PC largest charge PC Additional Materials Reading

Two small identical conductors, one with a charge of 45 μC and the other with charge -81 μC are brought together so that they touch, then separated. If the force they exert on each other has a size of 0.7 N, how far apart are the two conductors? (in m)(a) 7.14 m(b) 14.29 m(c) 6.85 m(d) 2.04 m(e) 4.08 m

Three identical metallic conducting spheres carry the following charges: q1 = +4.60 μC, q2 = +1.80 μC, and q3 = −1.60 μC. The spheres that carry the charges q1 and q2 are brought into contact. Then they are separated. After that, one of those two spheres is brought into contact with the third sphere that carries the charge q3; those two are then separated as well. How many excess (or deficiency) electrons make up the final charge on the third sphere?
