Question
Which charge feels the MOST force directed toward the right? a. A b. B c. C d. D What occurs when two charges are moved closer together? a. The electric field doubles. b. Coulomb's law takes effect. c. The total charge increases. d. The force between the charges increases. Which is the most correct statement regarding the drawing of electric field lines? a. Electric field lines always connect from one charge to another. b. Electric field lines always form closed loops. c. Electric field lines can start on a charge of either polarity. d. Electric field lines never cross each other. When a positive charge moves in the direction of the electric field, what happens to the electrical energy associated with the charge? a. It increases. b. It decreases. c. It remains the same. d. It sharply increases, and then decreases. What effect will be produced on a capacitor if the separation between the plates is increased? a. It will increase the charge. b. It will decrease the charge. c. It will increase the capacitance. d. It will decrease the capacitance.Explanation / Answer
1) Option d is correct. this is because charge D is experiencing repulsive force from C and A towards right. also, since distance between C and D isn't much, the repulsive force will be high
2)Option d is correct. Force between two charges is inversely proportional to square of distance between the charges. Hence,when they are brought closer, the force between the charges increses
3)option d is correct. Electric filed lines never cross each other
4)option a is correct. The potential energy associated with the charge increases
5)option d is correct. The capacitance is inversely proportional to distance between plates. Therefore, the capacitance decreases oif the plates are moved farther
