Answer:Answer on question#54317, Physics / ElectromagnetismQuestionAn electron moving at right angles to a uniform magnetic eldcompletes a circular orbit in 106sec. calculate the value of magneticeld.please give explaination for the formula that used.SolutionLorenz force acting on electron will cause centrifugal acceleration.Hence, we can write:qvB=mac=m2rAngular speed is related to period as= 2=T. ThereforeqvB=m42T2rqrB=m42T2rqB=m42T2Then the eld isB=mq42T2=9:110311:61019421012224:3T
