Question

Two identical objects A and B are at temperatures TA and TB respectively. Both objects are placed in a room with perfectly absorbing walls maintained at a temperature T(.TA>T>TB.) . The objects A and B attain the temperature T eventually. Select the correct statements from the following (A) A only emits radiations, while B only absorbs it until both attain the temperature T (B) A loses more heat by radiation than it absorbs, while B absorbs more radiation than it emits until they attain the temperature T (C) Both A and B only absorb radiation but do not emit it, until they attain the temperature T . (D) B only emits radiations, while A only absorbs it until both attain the temperature T

Every object emits and absorbs the radiations simultaneously. If the energy emitted is more than the energy absorbed temperature falls and vice versa.

$A$ only emits radiations, while $B$ only absorbs it until both attain the temperature $T$

$A$ loses more heat by radiation than it absorbs, while $B$ absorbs more radiation than it emits until they attain the temperature $T$

Both $A$ and $B$ only absorb radiation but do not emit it, until they attain the temperature $T$ .

$B$ only emits radiations, while $A$ only absorbs it until both attain the temperature $T$

Every object emits and absorbs the radiations simultaneously. If the energy emitted is more than the energy absorbed temperature falls and vice versa.
