A) \[1.25\times {{10}^{7}}\]
B) \[2.25\times {{10}^{7}}\]
C) \[3.25\times {{10}^{7}}\]
D) \[0.25\times {{10}^{7}}\]
Correct Answer: A
Solution :
\[=\frac{1}{2}\times 5\times {{\left( 10 \right)}^{2}}\] \[\text{V=750 }\!\!\times\!\!\text{ 1}{{\text{0}}^{\text{-3}}}\text{V}\] \[{{l}_{g}}=15\times {{10}^{-3}}A\] \[a=\frac{V}{{{l}_{g}}}\] \[=\frac{750\times {{10}^{-3}}}{15\times {{10}^{-3}}}\]
