Question

A circular metallic has a resistance $$10$$Ω. Area enclosed by the ring is $$0.5m2$$. The ring is placed in a uniform magnetic field with its plane perpendicular to the field. The magnetic field is decreasing at the rate of $$5$$ $$Tesla/$$$$sec$$. then total charge flown through a cross section of the wire of the ring in $$10$$ second is

Infinity Learn · Accepted Answer

ε  $$=$$ emf induced in the ring  $$=0.5$$×$$5volt=2.5voltCurrent$$ induced in the ring  $$=2.510A=0.25A$$∴ Charge flown in $$10$$ second $$=0.25$$×$$10coul=2.5coul$$
