An electron gun G emits electron of energy 2ke V travelling in the positive x – direction. The electrons are required to hit the spot S where GS = 0.1 m, and the line GS makes an angle of 60° with the x –axis as shown in the fig. A uniform magnetic field parallel to GS exists. Find parallel to GS exists in the region outside the electron gun. Find the minimum value of B needed to make the electrons hit S.
