In Millikan?s oil drop experiment, an oil drop of mass \[16\times {{10}^{-6}}kg\] is balanced by an electric field of \[{{10}^{6}}V/m.\] The charge in coulomb on the drop, assuming \[g=10\,m/{{s}^{2}}\] is [UP SEAT 2005]

• A.            \[6.2\times {{10}^{-11}}\]      
• B.            \[16\times {{10}^{-9}}\]          
• C.            \[16\times {{10}^{-11}}\]        
• D.            \[16\times {{10}^{-13}}\]
