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.
