5 Questions

1. The 3 charges → \(\frac {q}{2}\), -q, \(\frac {q}{2}\) are placed along the x axis at x = 0, x = r, x = 2 respectively. Find the resultant potential at a point A located at a distance y from charge q such that r << y.
2. Electric field and electric field intensity are related to electric potential.
3. The 3 charges → \(\frac {q}{2}\), -q, \(\frac {q}{2}\) are placed along the x axis at x = 0, x = r, x = 2 respectively. Find the resultant potential at a point A located at a distance y from charge q such that r << y.
4. There are infinite number of charges, each equal to ‘q’, which are placed along the X-axis at points x = 1, x = 4, x = 16, x = 64……..Then, determine the electric potential due to this system of charges at the point x = 0.
