A thermocouple of negligible resistance produces an e m f of 40 V C in the linear range of temperature A galvanometer of resistance 10 ohm whose sensitivity is 1 A div is employed with the thermocouple The smallest value of temperature difference that can be detected by the system will be a 0 25 C c 1 C 7 b 0 5 C d 0 1 C Charge q is uniformly spread on a thin ring of radius R The ring rotates about its axis with a uniform frequency fHz
