Question

True or false.

1. When a neutral glass rod is rubbed with a neutral silk cloth, the rod acquires a positive charge as the cloth acquires a negative charge as protons are transferred from the cloth to the rod

2. When an electron is taken from point A to point B along an electric field line that points from B to A, the electric potential energy of the system decreases

3. When a point charge is moved from point A to point B in an electric field, the total work done depends on the path that it takes

4. Three equivalent resistors wired in parallel have an effective resistance across the entire network that is equal to three times the value of a single resistor

5. A constant potential difference is maintained between the ends of a piece of wire. If the length of the wire is doubled, with no change to its cross sectional area, the current flowing through the wire is halved

6. A metal ring lies on a horizontal table. If the ring carries a clockwise current, a magnetic field will be generated that points into the table at the center of the ring
