Part A Two point charges, q1=2 MC and q2=5 /C are placed in vacuum. Each one experiences a 5.0 N electric force due to the other charge. If each of the charges is increased by a factor of 4 the electric force on each of them becomes O 1.3 N 50.0 N O 20.0 N O 80.0 N 0 0.3 N Submit Request Answer Provide FeedbackV PartA The charge on the square plates of a parallel-plate capacitor isQ. The distance between the plates is cl. The potential across the plates is maintained with constant voltage by a battery as the distance between the plates is reduces to d/G. The amount of charge on the plates is now equal to Part A In the circuit shown in the figure find the current through the 10 Ohm resistor. The emfs of the two batteries are E1=8 V and E2=4 V Note: depending on how you choose the directions of currents you may get a negative value. It does not necesarily mean that you made a mistake. Just use the magnitude (absolute value) of the current to choose your answer. 2.00 0 E1 a 3.00 Q 1.00 0 E2 4.00 0 b 10.00 0 O 0.24 A O 20.00 A 0.96 A O 1.44 A O 0.48 APart A Each plate of a parallel-plate air-filled capacitor has an area of 0.0010 m2, and the separation of the plates is 26 um .
