- Is the electric potential necessarily constant over the surface of a conductor? True or FalseIf the electric potential at a certain point is zero, does the electric field at that point have to be zero?(I) An electron acquires 6.45 x 10 -16 J of kinetic energy when it is accelerated by an electric field from plate A toplate B. What is the potential difference between the plates, and which plate is at the higher potential?
- If the magnitude of the electric field in air exceeds roughly 3 x 10° N/C, the air breaks down and a spark forms. For a two-disk capacitor of radius 51 cm with a gap of 4 mm, what is the maximum charge (plus and minus) that can be placed on the disks without a spark forming (which would permit charge to flow from one disk to the other)? The constant ɛo = 8.85 x 10 12 c?/(N-m2).A rod of length L lies along the x axis with its left end at the origin. It has a nonuniform charge density ? = ?x, where ? is a positive constant.
