1. A uniform electric eld of magnitude E = 335 MC makes an angle of 6 = 87.00with a plane surface of area A = 3.60 mi. Find the electric ux. 2. Find the change in electric potential energy associated with an electron red from x = 0.0400 m and reaching x = 0.130 m. 3. The voltage across an airlled parallelplate capacitor is measured to be 95.0 V. When a dielectric is inserted and completely lls the space between the plates, the voltage drops to 45.0 V. What is the dielectric constant of the inserted material? 4. A 14.0V battery is connected to a 4.7uF capacitor. How much energy is stored in the capacitor
