Unformatted text preview: Today 3/12 o Plates if charge l E-Field l Potential l HW: Plate Potential Due Friday, 3/14 (+) How big is E? (-) E net = 0 2 E =- 2 = + E = net E E net = 0 = Q/A Charged conducting plate Whats wrong with this picture? A = Area of one side L = /2 Charged conducting plate Free charge always goes to surface of conductor. R = /2 L = /2 Charged conducting plate R = /2 What is the electric field inside the conductor? E L = L /2 = /4 L = /2 Charged conducting plate R = /2 What is the electric field inside the conductor? E R = R /2 = /4 L = /2 Charged conducting plate R = /2 What is the electric field inside the conductor? The electric field is zero everywhere inside the conductor. Always, any conductor, no exceptions. q=+1C What happens if I let it go? KE = 0 KE = 100 J A B Assume the particle gains 100 joules of kinetic energy as it moves from A to B....
