find the no. of electron transferred between two ppints kept at a potential difference of 20V if 40 J of work is done

To find the number of electrons transferred between two points, we need to use the formula:

Q = W / V

Where:
- Q is the charge transferred (in Coulombs).
- W is the work done on the charge (in Joules).
- V is the potential difference (in Volts).

In this case, we are given that 40 J of work is done and the potential difference is 20V. Substituting these values into the formula, we have:

Q = 40 J / 20 V
Q = 2 C

Now, we need to find the number of electrons transferred. We know that one electron carries a charge of approximately 1.6 x 10^-19 C. Therefore, we can calculate the number of electrons transferred by dividing the charge Q by the charge of a single electron:

Number of electrons = Q / charge of one electron
Number of electrons = 2 C / (1.6 x 10^-19 C)
Number of electrons ≈ 1.25 x 10^19 electrons

Therefore, approximately 1.25 x 10^19 electrons are transferred between the two points.
