Electric field magnitude - Charge is uniformly distributed around a ring of radius R= 2.40 cm and the resulting electric field magnitude E is measured along the ring's central axis ( perpendicular to the plane of the ring). At what distance from the ring's center is E maximum?
In this question, I end up with E(total) = (q * z) / 4*Pi * e * (R^2 + z^2)^3/2
where e is the permittivity constan...
Physics - Electric Fields - Two Large metal plates of area 1.0m^2 face each other. They are 5.0 cm apart and have equal but opposite charges on their inner surfaces. If the magnitude E of the electric field between the plates is 55 N/C, what is the magnitude of the charge on each plate? Neglect edge effects.
electric field - An alpha particle (the nucleus of a helium atom) has a mass of 6.64x10-27kg and a charge of +2e. What are the (a)magnitude and (b)direction of the electric field that will balance the gravitational force on the particle?
I need to know the step by step setup and answer for this problem given the above information. thank you
