We have a charged half-ring with a radius of r= 18 cm and a linear charge density of of λ= 0.01 C/m. The centre of curvature of the half-ring is located at point O. How much work [in joules] does the electric field of the half-ring do when a charge of q= -7.9 μC is brought in from infinity to point O?
