Physics - Electrostatics Question with Solution | TestHub

A parallel plate capacitor with plates of length $\ell$ is included in a circuit as shown in figure. Given are the emf of the current source, its internal resistance r and the distance d between the plates. An electron with a velocity ${\mathrm{V}}_0$ flies into the capacitor, parallel to the plates. The resistance R should be connected in parallel with the capacitor so that the electron flies out of the capacitor at an angle of 37° to the plates is given as $\alpha \Omega$. Find $\frac{\alpha }{10}$.
