A charged particle X moves directly towards another charged particle Y. For the 'X plus Y' system, the total momentum is p and the total energy is E.

A charge particle moves towards another charged particle. Under what conditions the total momentum and the total energy of the system conserved ?

What is the total momentum of the system of particle?

Two particles P and Q each of mass 3m lie at rest on the X-axis at point (-a,0) and (+a,0) respectively. A third particle R of mass 2m intially at the origin moves towards the particle Q. IF all the collisions of the system of 3 particles are elastic and head on, the total number of collisions in the system is

A particle A of mass m and charge Q moves directly towards a fixed particle B , which has charge Q . The speed of A is a v when it is far away from B . The minimum separtion between the particles is not proportional to

A particle executing SHM has a total energy E. Another particle of twice the mass of the first particle executes SHM with 4 times the frequency and twice the amplitude of the first. Its total energy is

A charged particle moves through a region of uniform magnetic field perpendicularly. Is the momentum of particle affected ?
