A very small ball containing a charge -Q hangs from a light string between two vertical charged plates, as shown in the figure. When released from rest, the ball will;  

A parallel-plate capacitor with plate separation of 1.0 cm has square plates, each with an area of 6.0 × 10-2 m2. What is the capacitance of this capacitor if a dielectric material with a dielectric constant of 2.4 is placed between the plates, completely filling them? NOTE: Answer should be in decimals (i.e 3.1×10-6 would be 0.0000031) and include the unit with your answer.

A nonuniform electric field is directed along the x-axis at all points in space. This magnitude of the field varies with x, but not with respect to y or z. The axis of a cylindrical surface, 0.80 m long and 0.20 m in diameter, is aligned parallel to the x-axis, as shown in the figure. The electric fields E1 and E2, at the ends of the cylindrical surface, have magnitudes of 6000 N/C and 1000 N/C respectively, and are directed as shown. NOTE: Include the unit with your answer. To place a squared number in the answer, use the ^ (shift 6) after the number.   What is the net electric flux passing through the cylindrical surface?
