. Consider thé àrrangement shown, where distance between the plates of nerallel plate capacitor is d. When a potential difference V is applied between the plates, electrons are emitted from the negative plate with adligible initial velocity. These electrons are attracted towards the nositive plate creating a small electric current, which is registered in a micro-ammeter. What minimum magnetic field must be applied nerpendicular to the electric field in the capacitor so that the micro- ammeter registers no current? Denote charge and mass of an electron by symbols e and m respectively and neglect effects of gravity. Am:
