A conductor has `14.4 xx 10^(-19)` coulombs positive charge. The conductor has : (Charge on electron `= 1.6 xx 10^(-19)` coulombsA. 9 electron in excessB. 27 electron in shortC. 27 electrons in excessD. 9 electrons in short

Answer» Correct Answer - D
Positive charge shows the deficiency of electrons Number of electrons
`= (14.4 xx 10^(-19))/(1.6 xx 10^(-19))=9`.
