Charge of an electron is 0.00000000000000000016 coulomb. Find the charge of 5 electrons in standard form.
Charge of an electron is 0.00000000000000000016 coulomb = 1.6 × 10−19
Charge of 5 electrons = 5 × 1.6 × 10−19 = 8 × 10−19 coulomb
Question 3(ii) Express the number appearing in the following statements in standard form: Charge of an electron is 0.000,000,000,000,000,00016 coulomb.
