Question

If a negatively charged body comes in contact with a neutral body and 10 electrons flow towards the neutral body, then find the charge acquired by the neutral body.

• A. $16\times {10}^{-19}coulombs$
• B. $-16\times {10}^{-19}coulombs$
• C. $-1.6\times {10}^{-19}coulombs$
• D. $-1.6\times {10}^{-19}coulombs$

Answer 1

The correct option is B

$-16\times {10}^{-19}coulombs$

The neutral body has 10 more electrons than the number of protons, so the total charge acquired will be $10(–1.6\times {10}^{–19})=–16\times {10}^{–19}$ coulombs
