A) \[8.4\times {{10}^{6}}m/s.\]
B) \[2.76\times {{10}^{12}}C/kg\]
C) \[1.76\times {{10}^{11}}C/kg\]
D) \[0.76\times {{10}^{12}}C/kg\]
Correct Answer: A
Solution :
The dimensions of capacitance is \[C=[{{M}^{-1}}{{L}^{-2}}{{T}^{4}}{{A}^{2}}]\] The dimensions of resistance is \[R=M{{L}^{2}}{{T}^{-3}}{{A}^{-2}}\] Therefore, dimensions of CR is \[[{{M}^{-1}}{{L}^{-2}}{{T}^{4}}{{A}^{2}}]\,[M{{L}^{2}}{{T}^{-3}}{{A}^{-2}}]=[{{M}^{o}}{{L}^{o}}T{{A}^{o}}]\]You need to login to perform this action.
