A circular coil of radius 15 cm is placed in a uniform magnetic field of strength 0.70 T. The direction of the magnetic field is at an angle of 20o with the normal of the coil. What is the magnetic flux through the coil?

Two capacitors of values of 1.0 μF and 0.50 μF are connected in parallel. The system is hooked up to a 100 V battery. Find the electrical potential energy stored in the 1.0 μF capacitor.

Increasing the potential difference across the two plates of a capacitor will _________________.

Two point charges of 3.4 μC and 6.6 μC are 0.20 m apart. What is the electrical potential energy of the system?

A 10 gram particle mass carries a charge of 8.20 μC and is moving in an electric field of 125 N/C. What is the acceleration of the particle?

Two point charges of +30.0 μC and -9.00 μC are 20.0 cm apart, with the negative charge to the right of the positive charge. Taking to the right as being the positive x-direction, what is the electric field midway between these two charges?

A -4 nC point charge is located at -3 m along the x-axis. What is the electric potential at the origin?

A piece of wire 100 meters long has a resistance of 0.10 Ω. A current of 20 A runs through the wire, with a “voltage” at the input of 240 volts. (Note the input voltage of 240 volts is not the voltage drop…not delta(V)). What is the power delivered at the far end of the wire (or power “transmitted”)?

The electron volt (eV) is a unit of:

Two point charges, each of magnitude 6μC, exert a force of 1.4 N on each other. What is the distance between the charges?
