The charge on an electron is about 1.6 x 10^(-19) coulomb. How many digits are there after the decimal point when this is written as an ordinary decimal number?

Question

Accepted Answer

20. 1.6 x 10^(-19) = 0.00000000000000000016, which has 18 zeros then 1 and 6, i.e. 20 digits after the decimal point.

The charge on an electron is about $1.6 \times 1 0^{- 19}$ coulomb. How many digits are there after the decimal point when this is written as an ordinary decimal number?
