ahh pooooo never mind I've done it stupid mistake ... my bad

Homework Statement 2 points x and y, are along orthogonal directions from a 60uc charge. For x and y determine the potential difference between them. ( its in a vacuum also ) x= 10cm, y = 15cm Homework Equations okay, i know the equation is q/4*pi * EoEr *(1/ry - 1/rx) what i don't...

ahh pooo. so ε = εo*εr but i have the right idea for the rest of the equation? thanks for reply also.

Homework Statement A parallel plate capacitor has a charge of 50pC area = 10mm^2 dielectric material permittivity = 2.5 distance between plates = 0.5 mm find the electric field the potential difference between the 2 plates the energy stored in the capacitor Homework Equations...

cheers man, appreciate the help. good to know i am doing summit right for once:approve:e.

I think that is what i did, have i got the right idea?

Homework Statement a square of sides 10cm has four charges at each corner starting clockwise from top right they are 5,10,6 and 3nC. Determine the resultant electric field including magnitude and direction at the centre of the square. Owww and the medium is air. Finally what is the force on...
