An electorn is separated from the proton through a distance of 0.53 Å. Calculate the electric field at the location of the electron.

An electron and a proton travel through equal distances in the same uniform electric field E. Compare their time of travel. (Neglect gravity)

Two point charges +20nC and -20nC are separated by a distance of 0.10m. Calculate the electric field intensity at a perpendicular distance 0.10 m from the centre of a dipole.

An electron (mass m_(e ) )falls through a distance d in a uniform electric field of magnitude E. , The direction of the field is reversed keeping its magnitudes unchanged, and a proton(mass m_(p) ) falls through the same distance. If the times taken by the electrons and the protons to fall the distance d is t_("electron") and t_("proton") respectively, then the ratio t_("electron")//t_("proton") .
