tration 2 An electron gun G emits electrons of energy 2 keV 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 A uniform magnetic field B parallel to GS exists in the region outside the electron gun Find the minimum value of B needed to make the electrons hit S 60 60 S v cos 60 V v sin 60
