Question

Two spherical black bodies A and B made of the same material having masses 80 kg and 10 kg are maintained at temperatures $27^\circ C$ and $327^\circ C$ respectively. If P is the power radiated by body B, then the power radiated by body A is

• A. $4P$
• B. $\frac{P}{4}$
• C. $16P$
• D. $\frac{P}{16}$

Hint:

Radiated power: \[ P\propto AT^4 \] Always convert temperatures into Kelvin before applying Stefan's law.

Answer 1

The Correct Option is A
