P.S. i think problem is ill-framed..it is not cleaar whether a is the distance to centre of cavity or not???
hmm...the electric field inside the cavity is UNIFORM =Q(a+r)/4*pi*epsilon(0)*R3[if NOT to the centre]
=Qa/4*pi*epsilon(0)*R3[if TO the centre
thanx to negative thinking induced by subhomoy bakshi in gtalk![3][3][3][3]
