A) 1 : 256
B) 1 : 64
C) 1 : 4
D) 1 : 16
Correct Answer: A
Solution :
Hence: Initial temperature \[0.76\times {{10}^{12}}C/kg\] Final temperature \[(h=6.6\times {{10}^{-34}}J.s,c=3\times {{10}^{8}}m/s)\] Now from Stefans law, \[2\sqrt{2}:1\] So, \[m/{{s}^{2}}\] Hence, \[{{\tan }^{-1}}(1)\] \[{{\tan }^{-1}}(5)\]
