Question

5. If a charge of +2Q were placed at the origin (the crossing point of the vertical and horizontal lines) of the above figure, into which quadrant would it feel a net force? +4 +0 +30 +20 6. A uniform electric field is shown below. Draw equipotential surfaces. In which direction does the voltage decrease? If an electron is placed in the electric field at rest, draw the direction cf force. The electron moves from higher potential point to lower potential point or the other way around? If the potential difference between two locations of the electron is 5V, what is the chan SV? ge in potential energy of the electron. What is its speed at the end of the motion through SO-e 7. I have two capacitors of capacity 5pf and 8pF, respectively. How should I connect them to get a capacitor of capacity less than 5pF? 8. A capacitor consists of a set of two parallel plates of area A separated by a distance d This capacitor is connected to a battery that maintains a constant potential difference across the plates. If the separation between the plates is doubled, the electrical energy stored in the capacitor will be a. halved. b. unchanged. c. quartered d. doubled. e. quadrupled
