Q1: The cube shown has edge length of 1.40 m and is oriented as shown in a region of uniform electric field. Find the electric flux through the right face if the electric field is given in newtons per coulomb by: (a) 6.00 i ˆ , (b) -2.00 j ˆ , (c) -3.00 i ˆ + 4.00 k ˆ , (d) What is the total electric flux through the cube ? Q2: An electric charge Q is distributed uniformly through a non conducting sphere of radius 0 r . Determine the electric field outside and inside the sphere.

Q3: A solid, insulating sphere of radius a has a uniform charge density and a total charge Q. Concentric with this sphere is an uncharged, conducting hollow sphere whose inner and outer radii are b and c, as shown in the figure. Find the magnitude of the electric field in the regions: a) r < a. b) a < r < b. c) b < r < c. d) r > c.
