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

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.

To calculate the value of charge on a body that carries excess electrons, we need to know the elementary charge, which is the charge of a single electron or proton.

The elementary charge is approximately 1.6 × 10^-19 coulombs (C).

To determine the charge of a body carrying excess electrons, we can use the formula:

Charge = Number of Excess Electrons × Elementary Charge

In this case, the number of excess electrons is given as 20. So the calculation becomes:

Charge = 20 × (1.6 × 10^-19 C)

Calculating this expression, we get:

Charge = 3.2 × 10^-18 C

Therefore, the value of the charge on the body carrying 20 excess electrons is 3.2 × 10^-18 Coulombs.
