A parallel plate capacitor has its length, width and separation doubled. It fringing effects are neglected, to keep the capacitance same, the dielectric constant must be-A-halvedB-kept the sameC-doubledD-made 4 times-A-halved

Question

APTITUDE CRACK · Accepted Answer

A halved  . When dimensions are changed, A become four times and d becomes twice. Since ∈0 is constant, ∈r must be halved to keep C constant.
