What is the voltage drop across a $5.0\mathrm{~ω}$ resistor if the current running through it has a value of $5.0 \mathrm{~A}$?

A 15.0 k$\Omega$ resistor and a capacitor are connected in series, and then a 12.0 V potential difference is suddenly applied across them. The potential difference across the capacitor rises to 5.00 V in 1.30 $\mu$s. Find the capacitance of the capacitor.

Which of the following statements best explains why alpha emission is relatively common , but proton emission is extremely rare? Alpha particles occur in the nucleus.

A small conducting sphere has an excess of $1.5 \times 10^{12}$ electrons. Determine the electric potential and the magnitude of the electric field at a point $1.2 \mathrm{~m}$ from the sphere.

You are working on a research project in which you must control the direction of travel of electrons using deflection plates. You have devised the apparatus. The plates are of length $\ell=0.500 \mathrm{m}$ and are separated by a distance d = 3.00 cm. Electrons are fired at $v_{i}=5.00 \times 10^{6} \mathrm{m} / \mathrm{s}$ into a uniform electric field from the left edge of the lower, positive plate, aimed directly at the right edge of the upper, negative plate. Therefore, if there is no electric field between the plates, the electrons will follow the broken line in the figure. With an electric field existing between the plates, the electrons will follow a curved path, bending downward. You need to determine (a) the range of angles over which the electron can leave the apparatus and (b) the electric field required to give the maximum possible deviation angle.

A stream of electrons enters a uniform electric field between two charged parallel plates. The electrons do not strike either plate before exiting. Describe the path the electrons take while moving through the field and after exiting the field.

Using the results of above question, determine the electric field (direction and magnitude) at the midway point between the plates.

Four charged particles are at the corners of a square of side a as shown in figure. Determine the electric field at the location of charge q.
