Question

A wire, of length L (= 20 cm), is bent into a semicircular arc. If the two equal halves, of the arc, were each to be uniformly charged with charges ± Q, [|Q| = 10³ ε₀. Coulomb where ε₀ is the permittivity (in SI units) of free space] the net electric field at the centre O of the semicircular arc would be :
