Find the electric field at the centre of a uniformly charged semicircular ring of radius R. Linear charge density is lamda

Two semicircular rings lying in same plane, of uniform linear charge density lambda have radius r and 2r. They are joined using two straight uniformly charged wires of linear charge density lambda and length r as shown in figure. The magnitude of electric field at common centre of semi circular rings is -
