Two charge particle `P & Q` having same charge `1muC` and mass `4mukg` are initially kept at the distance of `1mm`. Charge `P` is fixed, then the velocity of charge parti `Q` when the separationbetween then becmoes `9mm`.

Two charged particles having charge 1 muC and -muC and of mass 50 gm each are held ar rest while their separtion is 2m . Find the relative velocity of the particles when their separation is 0.5m .

Two charged particles each having a charge +q and mass m are kept at a distance d. if they are in equilibrium under the gravitational force and the electric force between them, then the ratio q/m or specific charge of each particle is

A charged particle of mass m and charge q is kept initially at rest on a frictionless surface. Another charged particle of mass 4m and charge 2q starts moving with velocity v towards it. Calculate the distance of the closest approach for both the charged particles.

A particle A of charge 1 mu C is held fixed at a point P in free space . Another particle B of same charge and mass 4 mu g is kept at a distance of 1mm from P. If B is released then its velocity at a distance of 9 mm from P is (Take (1)/( 4pi epsilon_(0)) =9 xx 10^(9)Nm^(2) C^(-2))

Two identical charges, 5 muC each are fixed at a distance 8 cm and a charged particle of mass 9 xx 10^(-6) kg and charge -10 muC is placed at a distance 5 cm from each of them and is released. Find the speed of the particle when it is nearest to the two charges.

A particle of mass m and charge q is located midway between two fixed charged particles each having a charge q and at a distance 2L apart so that distance of this charge from each charge located at end is L. Assuming that the middle charge moves along the line joining the fixed charges. The frequency of oscillation when it is displaced slightly is
