Two protons are projected simultaneously from a fixed point with the same velocity v into a region, magnetic there exists a uniform magnetic field. The magnetic field strength at B and it si perpendicular to the initial direction of v. One proton starts at time t=0 and another proton at t = (pim)/(2qB) . The separation between them at time t = (pim)/(qB) (where, m and q are the mass and charge of proton), will be approximately

A proton is moving in a uniform magnetic field B in a circular path of radius a in a direction perpendicular to Z- axis along which field B exists. Calculate the angular momentum. If the radius is a and charge on proton is e.

The charge on alpha particle is ………The charge on proton

A particle which is four times in mass and two times in charge that of proton is called

Two positrons (e+) and two protons (p) are kept on four corners of a square of side a as shown in figure. The mass of proton is much larger than the mass of positron. Let q denotes the charge on the proton as well as the position then the kinetic energies of one of the positrons and one of the protons respectively after a very long time will be-

The mass of a H-atom is less than the sum of the masses of a proton and electron. Why is this?

The charge to mass ratio of alpha- particles is approximately to the charge to mass ratio of protons:

A nucleus has atomic number 11 and mass number 24. State the number of electrons, protons and neutrons in the nucleus
