A constant force of 10N is applied perpendicular to rod placed on 2 parallel rails .If the rod is having a resistance 10ohm but rails have zero resistance then maximum speed of rod is :(rails are long & frictionless & magnetic field is 10tesla). Solution) F=10N ,R=10Ω ,B=10T,
TOFIND ---->VELOCITY WE KNOW THAT F=qvB 10=(1.69*10^-19 )*V*10 V=1/1.6*10^-19 V=6.25*10^18
