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
Two point charges, each of mass m and charge q are released when they are at a distance from each other. What is the speed of each charged particle when they are at a distance 2r ?
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 charged particle of charge 'Q' is held fixed and another charged particle of mass 'm' and charge 'q' (of the same sign) is released from a distance 'r'. The impulse of the force exerted by the external agent on the fixed charge by the time distance between 'Q' and 'q' becomes 2 r is
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. Assuming that the middle charge moves along the line joining the fixed charges, calculate the frequency of oscillation when it is displaced slightly.
A particle of mass 2 g and charge 1 muC is held at rest on a frictionless surface at a distance of 1m from a fixed charge of 1 mC. If the particle is released it will be repelled. The speed of the particle when it is at distance of 10 m from fixed charge is :
