1) a car battery is rated at 90 amphour. How much charge isavailable in the battery?
2) A +2.6 uc point charge is placed at the center of a cube withsides of length 7.5cm. What is the electric flux through two sidesof the cube?
3) The amount of charge flowing though a circuit caries withtime according to.. q(t)=(0.2t2-0.3t), with q incoulombs and t in seconds. Find the current through the circuit att = 1.5 seconds.
4) Calculate the acceleration of an electron placed in a uniformelectric field of magnitude 4.5*105 N/C.
