Question

what is the total charge in coulomb of 75kg of electron? Related:  Electric Charges Introduction - Electric Charges and Field, Class 12, Physics?

Answer

Charge on one electron = 1.6 × 10⁻¹⁹ C,
i.e, 9.1 × 10⁻³¹ kg contains 1.6 × 10⁻¹⁹ C...
so, 75 kg contains (1.6 × 10⁻¹⁹ × 75)/(9.1 × 10⁻³¹) = 1.38 × 10¹³ electrons...

Answer

Answer:

Electric Charges Introduction

Electric charges are the fundamental property of matter. There are two types of electric charges: positive and negative. Like charges repel each other, and unlike charges attract each other. The unit of electric charge is coulomb (C).

Charge of an electron

The charge of an electron is negative and is equal to -1.602 x 10^-19 C.

Total charge in coulombs of 75kg of electron

To find the total charge in coulombs of 75kg of electrons, we need to know the number of electrons in 75kg of matter.

The mass of one electron is 9.11 x 10^-31 kg.

Therefore, the number of electrons in 75kg of matter can be calculated as:

Number of electrons = (75 kg) / (9.11 x 10^-31 kg/electron)

Number of electrons = 8.23 x 10^33 electrons

The total charge in coulombs of 75kg of electrons can be calculated as:

Total charge = (Number of electrons) x (Charge of one electron)

Total charge = (8.23 x 10^33 electrons) x (-1.602 x 10^-19 C/electron)

Total charge = -1.32 x 10^15 C

Therefore, the total charge in coulombs of 75kg of electrons is -1.32 x 10^15 C.
