Question

A conductor has $14.4\times {10}^{-19}$ coulombs positive charge. The conductor has (Charge on electron $1.6\times 10-19$coulombs )

• A. 9 electrons in excess
• B. 27 electrons in short
• C. 27 electrons in excess
• D. 9 electrons in short

Answer 1

The correct option is D 9 electrons in short

Positive charge shows the deficiency of electrons. number of electrons $=\frac{14.4\times {10}^{-19}}{1.6\times {10}^{-19}}=9$
