A long solenoid of diameter 0.1 m has 2 10turns per meter. At the centre of the solenoid. acoil of 100 turns and radius 0.01 m is placed withits axis coinciding with the solenoid axis. Thecurrent in the solenoid reduces at a constanrate to 0A from 4 Ain 005s If the resistance ofthe coil is 10,2Ω, the total charge flowingthrough the coil during this time is(a) 16 uC(c) 16 TIG |
