Question 2 (5 points). Electrostatic work

A point charge $Q = +5\text{ nC}$ is located at the origin of coordinates $(0, 0)$.

a.

Determine the energy required to bring a test charge $q = +1\text{ nC}$ from infinity to point $A(3\text{ m}, 4\text{ m})$.

b.

If the charge $q$ is subsequently displaced from point $A(3\text{ m}, 4\text{ m})$ to point $B(4\text{ m}, 3\text{ m})$, what is the amount of work required to perform this second displacement?
