Question

At a temperatur of 30°C, the susceptibility of a ferromagnetic material is found to be $\chi$. Its susceptibility at 333°C is(a) $\chi$(b) $0.5\chi$(c) $2\chi$(d) $11.1\chi$

Answer 1

Hey mate

It's a simple calculation.

${Using\:unitary\:method}$

At 30°C = x

Then, at 1℃ = x/30

Then at 333℃ = x/30 * 333

At 333℃ = 11.1 x

Hence the option is (D)
