EE 101; Homework 2: DUE OCTOBER 16 TH Thursday 2PM; (THERE WILL BE A COLLECTION BOX IN MARIKO WALTON’S CUBICLE ON THE 6 TH FLOOR OF ENGR IV.) 1. Three point charges, each with q=3 nC, are located at the corners of a triangle in the x y plane, with one corner at the origin, another at (2cm,0,0), and the third at (0, 2cm, 0). Please find the force acting on the charge located at the origin. 2. A line of charge with uniform density ρ l =1( μ C/m) exists in air along the z -axis between z= 0 and z= 5 cm. Find E at (0,10 cm,0)? 3. A circular ring of charge of radius a lies in the x y plane and is centered at the origin. If the ring is in air and carries a uniform charge density of ρ Please show that the electric potential at (0,0,z) is given by (a) 22 0 V= 2 a az ε ⋅+ (b) find the corresponding E field.
