an object has 2.0x 10^19 more electrons than protons. What is the net electric charge of this object in coulomb?
2.0x10^19-protons is net electric charge since electrons are negative and protons are positive.Is the protons given also?
To determine the net electric charge of the object in coulombs, we need to calculate the difference in the number of electrons and protons and then multiply it by the elementary charge (e). The elementary charge is approximately 1.6 × 10^(-19) coulombs.
Given that the object has 2.0 × 10^19 more electrons than protons, we can calculate the net electric charge as follows:
Net electric charge = (Number of electrons - Number of protons) × Elementary charge
Number of electrons = Number of protons + 2.0 × 10^19
Net electric charge = (2.0 × 10^19) × (1.6 × 10^(-19))
Net electric charge = 3.2 × 10
Therefore, the net electric charge of the object is 3.2 × 10 coulombs.
To determine the net electric charge of an object, you need to calculate the difference between the number of electrons and the number of protons. The elementary charge of an electron is approximately 1.6 x 10^(-19) coulomb, and the charge of a proton is the same but with a positive sign.
Let's start by converting the given number of excess electrons into a total charge:
1. Calculate the number of excess electrons:
2.0 x 10^19 excess electrons
2. Calculate the total charge:
Total charge = (number of electrons – number of protons) x elementary charge
Given that there are 2.0 x 10^19 more electrons than protons, the number of electrons would be 2.0 x 10^19 + 1 (one extra electron for the overall positive charge of the protons).
Total charge = (2.0 x 10^19 + 1 - 1) x (1.6 x 10^(-19) C)
= 2.0 x 10^19 x (1.6 x 10^(-19) C)
= 3.2 x 10^0 C
= 3.2 C
Therefore, the net electric charge of the object is 3.2 coulomb.
