show an electric dipole formed by two . particles fixed at the ends of a light rod of length l. The . mass of each particle is m and the charges are -q and . +q . The system is placed in such a way that the dipole . axis is parallel to a uniform electric field E that exist . in the region. The dipole is slightly rotated abut its . centre and released. Show that for small angular . desplacement, the motin is anguler sumple harmonic . and find its time period.

A charged particle of mass m and charge q is released from rest in an electric field of constant magnitude E . The kinetic energy of the particle after time t is

A simple pendulum has a length l & mass of bob m. The bob is given a charge q coulomb. The pendulum is suspended in a uniform horizontal electric field of strength E as shown in figure, then calculate the time period of oscillation when bob is slightly displaced from its mean position.

A particle of mass m and charge q is released from rest in uniform electric field of intensity E. Calculate the kinetic energy it attains afect moving a distance x between the plates.

A particle of mass m and charge -q is projected from the origin with a horizontal speed v into an electric field of intensity E directed downward. Choose the wrong statement. Neglect gravity

A particle of mass m and charge q is thrown in a region where uniform gravitational field and electric field are present. The path of particle:

An oil drop of mass m and charge +q is balanced in vaccum by a uniform electric field of intensity E . the direction of this field should be
