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

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

Two point charges each 50 mu C are fixed on y -axis at y = + 4 m and y = - 4m . Another charged particle having charge -50 mu C and mass 20 g is moving along the positive x -axis. When it is at x = -3 m , its speed is 20 m//sec . Find the speed of charged particle when it reaches to origin. Also , find distance of charged particle from origin , when its kinetic energy becomes zero.
