Two identical objects A and B are at temperature `T_(A)` and `T_(B)` respectively. Both objects are placed in a room with perfectly absorbing walls maintained at temperature `T(T_(A)gt TgtT_(B))`
Statement-1: The objects A and B attain the temperature T eventually.
Statement-2: A only emits radiation while B only absorbs until radiation both attain the temperature T

A

‘ A ’ only emits radiations while B only absorbs them until both attain temperature

B

A loses more radiations than it absorbs while B absorbs more radiations that it emits until temperature T is attained

C

Both A and B only absorb radiations until they attain temperature T

D

Both A and B only emit radiations until they attain temperature T
