	The magnitude of electric field intensity $E$is such that, an electron placed in it would experience an electrical force equal to its weight is given by
	A conductor with a positive charge
	An electron and a proton are in a uniform electric field, the ratio of their accelerations will be
	Two parallel plates have equal and opposite charge. When the space between them is evacuated, the electric field between the plates is $2 \times {10^5}V/m$. When the space is filled with dielectric, the electric field becomes $1 \times {10^5}V/m$. The dielectric constant of the dielectric material
