What is the value of charge of a body that Carries 20 excess electrons

6 answers

20•e =20•1.6•10^-19 =3.2•10^-18 C
-20 e,

where e = 1.602*10^-19 Coulombs.

Do the multiplication.
Elena forgot the minus sign
q=20*(1. 6*10^-19)
q=32*10^-19
q=3. 2*10^-18C
q=20*(-1. 6*10^-19)
q=-32*10^-19
q=-3. 2*10^-18C
-3. 2*10^-18C is the correct answer.
