Two neutral metal spheres are on plastic stands. The spheres are touching each other. The spheres are solid metal all the way through - they are not shells. You bring a negatively charged plastic rod directly to the left of the left sphere, not quite touching it While the rod is still there, you move the right sphere a very short distance to the right so that the spheres no longer touch each other. Then you withdraw the rod. You...

1. Two long, straight wires cross
each other at right angles without touching, and each carries the
same current as in the figure. Which of the following statements
are true regarding the total magnetic field at the various points
due to the two wires ? (There may be more than one correct
statement.) (a) The field is strongest at points B and D. (b) The
field is strongest at points A and C. (c) The field is out of the...

Two infinite line charges (charged rods/cylinders, E=k*lambda/D)) make a 90 degree angle with each other. Each has charge density lambda=0.1C/m. What is the electric field at a distance of 0.05m above each rod? Make sure to draw a picture to indicate direction.

A certain sphere is nonconducting. This sphere has six point charges equally spaced from each other fixed to a surface on the sphere. A) If each point charge has a charge Q, and the radius of the sphere is R, what is the magnitude of the net electric field, E, at one point charge due to the other 5? Please only answer with Q, R and k. B) Now consider that an actual balloon, when inflated, will exert a force,...

two point charges exert an attractive force of 5.0 N on each other. How much force would they exert on each other if the distance between them were: a) ten times as great b) one-tenth as great c) how would your answers to a and b be altered if at all if the forces the charges exert on each other were repulsive rather than attractive? (please include all steps/formulas used)

Two charges (a negative one and a positive one) are 18 cm apart from each other. If there is a 36.7 N force on the negative charge then a) What is the magnitude of the force on the positive charge? b) What is the charge on the positive particle? c) If the positive particle were removed what would be the magnitude of the Electric field at the spot where the positive particle used to be?
