Question

what is the total charge on 25kg of electrons​

Answer 1

Explanation:

Charge of one electron = -1.6 × 10^(-19) C

Number of electrons in 1kg = 1.0978 × 10^30

Therefore, number of electrons in 25 kg

= 1.0978 × 10^30 × 25

Charge on 25kg electrons

= (1.0978 × 10^30 × 25) × (-1.6 × 10^(-19)) C

= - 43.912 × 10¹¹ C

Answer 2

Answer:

The charge qe on a single electron is −1.6×10−19C. Let us now determine the total charge on n number of electrons. The total charge q on n number of electrons is the product of the number of electrons and the charge on a single electron. Substitute 8.33×1031 for n and 1.6×10−19C for qe in the above equation.
