```										$\small V_{\infty}=0\\ V_{inside}=(-Q/4\pi \epsilonR +Q/4\pi \epsilon2R)=-Q/4\pi \epsilon2R$Because charge appearing on the inner surface will be -Q and since the charge was originally zero so charge on outside =+Q.$\small W=-\Delta V \\=>W=-(V_{\infty}-V_0)=V_{0}$Thanks & RegardsArun KumarIIT DelhiAskiitians Faculty

why the electric field inside a conductor placed inside an external electric field is zero

It only happens in electrostats as in electrostatics free charges in a good conductor reside only on the surface. and after coming on surface they will align themselves in such a fashion...
