A) \[3\times {{10}^{8}}\,m/s\]
B) \[6.46\,\times {{10}^{5}}\,m/s\]
C) \[10.36\,\times {{10}^{5}}\,m/s\]
D) \[8.54\,\times {{10}^{6}}\,m/s\]
Correct Answer: B
Solution :
Energy corresponding to \[\frac{5}{6}\] \[\frac{6}{7}\] \[\frac{1}{86400}{{/}^{0}}C\] Maximum kinetic energy \[\frac{1}{43200}{{/}^{0}}C\] \[\frac{1}{44400}{{/}^{0}}C\] \[\frac{1}{28800}{{/}^{0}}C\] Now, \[9\times {{10}^{-1}}C\] \[9\times {{10}^{-6}}C\] or \[8.85\times {{10}^{-13}}C\] or \[v_{\max }^{2}\,=0.418\,\times {{10}^{12}}=41.8\,\times {{10}^{10}}\] or \[1.8\times {{10}^{-14}}C\]
