An electric dipole is formed by two particles fixed at the end of a light rod of length L. Mass m and 2m with charge q and – q. The system is placed in such a way that the dipole axis is parallel to a uniform electric field. If the dipole is slightly rotated about its center then show that for small angular displacement it’s an shm. And find time period

Two charged metal plates in vacuum are 10 cm apart. A uniform electric field of intensity ( 45/16 )×10^ 3 N/C is applied between the plates. An electron is released between the plates from rest at a point just outside the negative plate. (a) Calculate how long (t) will the electron take to reach the other plate? (b) At what velocity (v) will it be electron take to hits the other plate?

Protons are projected with an initial speed vi = 6 km/s from a field-free region through a plane and into a region where a uniform electric field E with arrow = −900 ĵ N/C is present above the plane as shown in in the figure below. The initial velocity vector of the protons makes an angle θ with the plane. The protons are to hit a target that lies at a horizontal distance of R = 1.15 mm from the point where the protons cross the plane and enter the electric field. We wish to find the angle θ at which the protons must pass through the plane to strike the target.
