A long solenoid of the cross sectional radius R has a thin insulated wire ring tightly put on its winding One half of the ring has the resistance 10 times that of the other half The magnetic induction produced by the solenoid varies with time as B bt whose b is a constant If the magnitude of the electric field strength in the ring is Rb 9 where p and q are the smallest positive integers then what is the value of p q
