Two spherical bodies

A

(radius 6 cm) and

B

(radius 18 cm) are at temperature

T_1

and

T_2

, respectively. The maximum intensity in the emission spectrum of

A

is at 500 nm and in that of

B

is at 1500 nm. Considering them to be black bodies, what will be the ratio of the rate of total energy radiated by

A

to that of

B
