Question

If A has a +5 relative unit charge, then the absolute charge is equal to:

• A. $+5$ coulomb
• B. $+8.01\times {10}^{-19}$ coulombs
• C. $+5.01\times {10}^{-19}$ coulomb
• D. None of these

Answer 1

The correct option is B $+8.01\times {10}^{-19}$ coulombs

+1 relative unit charge is equal to $1.602\times {10}^{-19}$ coulomb.
So, +5 relative unit charge $=5\times 1.602\times {10}^{-19}=+8.01\times {10}^{-19}$ coulomb
