Question

1. How much work is required to move a charge of 4 nC from a point 2m away to a point 0.5m away from a point charge of 60 nC? What is the potential difference between these points?

2. A point charge q₁ = 4.00 nC is placed at the origin, and a second point charge q₂ = -3.00 nC is placed on the x-axis at x= +20.0 cm. A third point charge q₃ = 2.00 nC is to be placed on the x-axis between q₁ and q₂. Let the potential energy of the three charges be zero when they are infinitely far apart.

a) what is the potential energy of the system of the three charges if q₃ is placed at x= +10.0 cm?
