A parallel-plate capacitor partially filled with a dielectric slab of dielectric constant K is connected to a cell of emf V, as shown. The plate separation is D. Select the correct statement.

Question

G1 Physics · Accepted Answer

Both P and P′ lie between the same equipotential plates separated by D. In the side-by-side dielectric arrangement the potential gradient is V/D in each region, so E(P)=E(P′). Hence C.
