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

• physics -

20•e =20•1.6•10^-19 =3.2•10^-18 C

• physics -

-20 e,

where e = 1.602*10^-19 Coulombs.

Do the multiplication.

• physics -

Elena forgot the minus sign

• physics -

q=20*(1. 6*10^-19)
q=32*10^-19
q=3. 2*10^-18C

• physics -

q=20*(-1. 6*10^-19)
q=-32*10^-19
q=-3. 2*10^-18C

• physics -

-3. 2*10^-18C is the correct answer.
