The figure shows two fixed charges near points A and B. Assume the potential at infinity is zero.
a) Find the electric potential at A.
b) Find the potential difference V_A - V_B
c) Charge q₀ moves from A to B. Find the change in q₀’s electric potential energy.
d) The charge is influenced only by electrostatic forces. If it starts at A with 30 J of kinetic energy, what is its kinetic energy at B?
