A uniform electric field, Ed of magnitude 1x106 V.m-1-1 MV.m-1 is set up inside a large block of dielectric of relative permittivity Er = 3.41. A cavity is cut out of the block in the shape of a short cylinder whose ends are perpendicular to the electric field (b) What is the electric field, EC inside the cavity? Give your answer here in units of MV.m-1 [2 marks] Use scientific notation if necessary in your answers (c) What is the magnitude of the surface density (polarisation P) of induced charges at the flat, end surfaces of the cavity ? Give your answer here in units of C.m2. Use scientific notation if necessary in your answers [2 marks]
