Physic AP 2 - Electrostatics Test - Sam and Eddie1. The electron volt is a measure of (A) charge (B) energy (C) impulse (D) momentum (E) velocity 2. A solid conducting sphere is given a positive charge Q. How is the charge Q distributed in or on the sphere? 3. A parallel–plate capacitor is charged by connection to a battery. If the battery is disconnected and the separation between the plates is increased, what will happen to the charge on the capacitor and the voltageacross it? Questions 4-5A point P is 0.50 meter from a point charge of 5.0 × 10–8 coulomb. 4. The intensity of the electric field at point P is most nearly 5. The electric potential at point P is most nearly (A) 2.5 × l0–8 V (B) 2.5 × 101 V (C) 9.0 × 102 V (D) 1.8 × 103 V (E) 7.5 × 103 V 6. One joule of work is needed to move one coulomb of charge from one point to another with no change in velocity. Which of the following is true between the two points? Questions 7 – 8Two positive charges of magnitude q are each a distance d from the origin A of a coordinate system as shown above.
