Question

The force experienced by a chloride ion having $4$ electrons removed, when placed in an electric field of intensity $2N{C}^{-1}$ is :

• A. $12.8\times {10}^{-19}N$
• B. $12.8\times {10}^{-16}N$
• C. $6.4\times {10}^{-19}N$
• D. $6.4\times {10}^{-16}N$

Answer 1

The correct option is A $12.8\times {10}^{-19}N$

When $4e^{-}$ are removed charge on chloride ion
$=4\times 1\cdot 6\times {10}^{-19}C.$
Now $F=Eq$
$=2\times 4\times 1\cdot 6\times {10}^{-19}$
$F=12\cdot 8\times {10}^{-19}N$
