An infinite line charge produce a field of \[7.182\times {{10}^{8}}\,N/C\] at a distance of 2 cm. The linear charge density is [MH CET 2004]

• A.                    \[7.27\times {{10}^{-4}}\,C/m\]
• B.                                      \[7.98\times {{10}^{-4}}\,C/m\]
• C.                    \[7.11\times {{10}^{-4}}\,C/m\]
• D.                                      \[7.04\times {{10}^{-4}}\,C/m\]
