m A block of mass m kept on a rough horizontal surface is connected to a dielectric slab of mass and 5 dielectric constant k by means of a light and inextensible string passing over a fixed pulley The dielectric can completely fill the space between the plates of parallel plate capacitor each plate is square shaped with side Seperation between plates kept in vertical position is d The coefficient of friction between block and horizontal surface is and ignore any other friction Find the minimum value of emf of the battery so that after closing the switch the block will move mg Lit mg G 2mg 4mg
