A sphere P(emissivity=1) of radius 2R and and another sphere Q(emissivity =1/2) of radius R are placed in vacuum at some distance.There are no other objects. The temperature of the sphere Q is maintained at 200K by the means of a heater. A fraction 1/32 of the power emitted by the sphere Q falls on the sphere P. If the equilibrium temperature of the sphere P is 10 T, find the value of T.
