Consider a ring of charge with radius 4 cm and total charge +2.2 μC distributed uniformly on the ring. The ring is placed on the xz plane with and the symmetry axis perpendicular to its plane is along the y-axis (see Figure). Which of the following gives the work done by the electric force in Joules in moving a point charge +1.1 μC from point A(0, 4√3,0) to B(0,0,0)? (k = 4 Answer: = 9 × 10⁹ Nm²/C²) X B a A
