A wire
A wire, of length L(=10cm), is bent into a semi-circular arc. If the two equal halves, of the arc, were each to be uniformly charged with charges ±Q,[|Q|=10^6 ε0 Coulomb where ε0 is the permittivity (in SI units) of free space. The net electric field at the centre O of the semi-circular arc would be :
