Kindly do not take same as reference. 15. Consider the arrangement shown, where distance between the plates ofbetween the plates, electrons are emitted from the negative plate witha parallel plate capacitor is d. When a potential difference V is appliedTrom the origin. :Cose9B2Bween the plates, electrons are emitted from the negative plate withogligible initial velocity. These electrons are attracted towards thenositive plate creating a small electric current, which is registered in amicro-ammeter. What minimum magnetic field must be appliedperpendicular to the electric field in the capacitor so that the micro-ammeter registers no current? Denote charge and mass of an electronby symbols e and m respectively and neglect effects of gravity.hmiはよ)Ams:2mv

Concept As the electrons are subjected to the magnetic field and the electric field simultaneously,…

When a potential difference V is applied reen the plates, electrons are emitted from the negative plate with sogligible 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: + 2mv a)
