Consider two particles A and B having equal charges
. and placed at some distance. The particle A is slightly
. displaced towards B. Does the force on B increase as
. soon as th particle A is displaced? Does the force on
. the particle A increase as soon as it is displaced?

Two particles A and B having equal charges are placed at distance d apart. A third charged particle placed on the perpendicular bisector at a distance x will experience the maximum Coulomb’s force when :

If distance covered by a particle is zero, what can be its displacement ?

Two particles having charge Q_(1) and Q_(2) , when kept at a certain distance exert a force F on each other . If the distance between the two particles is reduced to half and the charge on each particle is doubled , the force between the particles would be

Force F on a particle moving in a straight line varies with distance d as shown in figure The work done on the particle during its displacement of 12 m is

The displacement time curve of a particle is shown in the figure. The external force acting on the particle is :

If the displacement of a particle is zero, then distance covered by it

Force F on a particle moving in a straight line varies with distance d as shown is figure. The work done on the particle during its displacement of 10 m is :-

A force F = p+qx acts on a particle in the X - direction , where p and q are constants . If the particle is displaced from x = a to x = b , find the work done by the force .

Two points charges , each Q , are fixed at separation 2d . A charged particle having charge q and mass m is placed between them. (a) Now this charged particle is slightly displaced along the line joining the charges , slow that it will execute simple harmonic motion and find the time period of oscillation. (b) If charge q is negative and it is displaced slightly perpendicular to the line joining the charges , repeat the part (a) .
