#### A wire, of length L(=20 cm), is bent into a semi-circular arc. If the two equal halves, of the arc, were each to be uniformly charged with charges Coulomb where is the permittivity (in SI units) of free space] the net electric field at the centre O of the semi-circular arc would be : Option 1) Option 2) Option 3) Option 4)

As we learnt in

Linear charge distribution -

charge per unit length.

- wherein
