Question

29. An electron is accelerated to the right from rest by a potential difference of 2kV. It then enters a region lie in of constant magnetic field pointing into the page of strength B-3μΤ. This region happens to also between a capacitor with C-5μF and separation distance cm) If the emf of the battery is 10V and R-3M2, for how lo undeflected? Is the battery in the figure drawn correctly? ng must this capacitor be charged such that the electron moves through the region ㄨ義義義義

please write neatly

Answer #1

first to move the electron undeflected magnetic force must be balanced by electric force and after that we can calculate the time required to charge the capacitor so that it electric force  developed between the capacitor balances the magnetic force as solved in detailed
