A) \[1\times {{10}^{-15}}\]
B) \[1\times {{10}^{-10}}\]
C) \[1\times {{10}^{-23}}\]
D) \[1\times {{10}^{-27}}\]
Correct Answer: C
Solution :
\[i=6.6\times {{10}^{15}}\times 1.6\times {{10}^{-19}}=10.5\times {{10}^{-4}}amp\] \[A=\pi {{R}^{2}}=3.142\times {{\left( 0.528 \right)}^{2}}\times {{10}^{-20}}{{m}^{2}}\] Þ\[M=iA=10.5\times {{10}^{-4}}\times 3.142\times {{\left( 0.528 \right)}^{2}}\times {{10}^{-20}}\] \[=10\times {{10}^{-24}}units=1\times {{10}^{-23}}units\]You need to login to perform this action.
