There are two charges in the xy plane and no other nearby charges. There is a 9 millicoulomb charge at the origin and a 8 millicoulomb charge at x=21 meters and y=35 meters. What is the x component of the force on the charge at the origin caused by the other charge? Give your answer in Newtons.
Two identical beads each have a mass m and charge q. When placed in a hemispherical bowl of radius R with frictionless, nonconducting walls, the beads move, and at equilibrium, they are a distance d apart (as shown). (a) Determine the charge q on each bead. (b) Determine the charge required for d to become equal to 2R.
Question 1.
Two conductive spheres have the radius R1 = 0.2 m and R2 = 0.1 m. The
spheres have the charge ql = 6 nC and q2 = -4 nC and are located at a
distance from each other that is much larger than the radius of the spheres.
A conductive wire is inserted between them so that charge can travel from
one sphere to the other. The wire is then removed. How is the charge now
distributed on the two spheres?
