A capacitor has a capacitance of 80.0 μF. If you want to store 155 J of electric potential energy in this capacitor, what potential difference do you need to apply to the plates?

A small plastic sphere of mass (m) has a charge q = 2.0 C. An upward pointing uniform electric field of magnitude 5.0 × 10-3 N/C supports and balances the weight of the sphere. Find the mass (m) of the sphere.

A copper ring of radius R lies in a uniform magnetic pointed into the screen, as shown below. The field is uniformly decreasing in magnitude.       The induced current in the ring is
