I know how to find the capiciatnce in a parrallel but have no idea how to find out the electric field. Any help? I don't have a textbook with me so I am pretty much screwed :)
A parallel plate capictor with a plate area of 1.8 m^2 and a separation of 0.1 mm is charged to 200V.
a. what is the electric field bwt. the plates?
b. what is the energy/unit volume in the space between the plates?
c. Find the capacitance C
d. Calculate the total energy stored in this...

An isolated spherical conductor of radius 20cm is charged to 4k V (i.e. 4000 V).
a. How much charge is on the conductor?
b. What is the capacitance of the sphere?
c. how does the capacitance change if the spere is charged to 8 k V (8000)?
A barium nucleus has a charge of q = +56e (where e is the proton charge).
a. find the potential V at a radius of 10-12 m from the Nucleus. If a Proton is released from this point, how fast will it be moving when it is 1 m from the nucleus? Note: Assume V (infinity=0)
Any help?

A uniform electric field E exists between two conducting plates separated by a distance d. An electron is released from rest at the negative plate and is attracted to the positive plate.(a) Find its kinetic energy in terns of E, d and the electronic charge. (b) If E...
Heres another similar question:
Two point charges, q1= 0.50 x 10^-9 C and q2= 8.00 x 10^-9 C are seperayed by a distance of 1.20 m. At what point along the line joining the points charges, is the total electric field die to the two charges equal to zero?
Hey I am studying for a test, These are one the questions. Anyone know how to solve this?
Two point charges repel each other with a force of 2.0 x 10^-9 N. One of the point charges carries twice the amount of charge carried by the other. When the two charges are moved 0.1 m farther apart...
