Question

1. two identical charges, 8.00cm apart, each exert a force of magnitude 150N on the other. The value of each charge is:

2. A very long straight thread of length L carries aa charge of Q spread uniformly along its length. What is the magnitude of the electric field at a radial distance r from the thread? (Hint : consider a gaussuan cylinder concentric with thread. )

3. A parallel plate capacitor has circular plates of radius 6.00cm separated by a distance of 2.00mm if a potential difference of 50.00V is applied across the plates, how much charge is on the capacitor?

Explanation / Answer

The force of two charge particles on eachother is just: F = 1/(4*pi*eta)*q1*q2/R^2 eta is the permitivity of a vacuum q1 and q2 is the charge of each particle and if they're they same then its q^2 R is the distance between the two particles you have the force and the distance, the rest is just a constant leaving you with charge solve for q
