1. The problem statement, all variables and given/known data Q1. A non-uniform electric field is given by the expression E=3yi+2zj-k. Determine the electric field flux through a rectangle in the xy plane, extending from x=0 to x=20 cm and y=0 to y=15cm Q2. A point charge q1 = +5nc is placed at the center of a non-conducting sphere (radius a=3) which has a chrage of Q= -8nc distributed uniformly throughout its volume. find: a)the electric field at r=2m b)the electric field for r=5m If the non-conducting sphere is nw replaced with a conducting hollow sphere,having the same total charge, and the same radius. The cavity has a radius of 0.5m FIND: C)The electric field at r=2m D)The electric field at r=5m 2. Relevant equations Q1. ø=EAcosθ Q2. Electricfield x area = Qenclosed/epsilon nod 3.
