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.
