CBSE Class 12-science Physics Magnetic Lorentz Force

• what is charge
• A proton and an alpha particle both enter region of uniform magnetic field B, moving at right angles to the field B . if the radius of circular orbits for both the particals is equal and the kinetic energy aquried by the proton is 1 MeV , the energy acquired by the alpha particle will be ?
• A 2MeV proton is moving perpendicular to a magnetic field of 10 Tesla. what is the magnetic force on the proton? (mass of proton=1.6×10^-27 kg)
• As we know, work done by Magnetic force is always zero in moving a charged particle./So it cannot change speed of charged particle. MY doubt is that, can magnetic force change direction of motion of charged particle?
• Sir , if a magnetic field is increasing in a cylindrical volume at a constant rate. then what will be direction of instantaneous acceleration experienced by an electron placed inside cylinder but not on center?
• pls explain
  
• Hii
  
• What do you mean by magnetic Lorentz force?
• When will be the force experienced by moving charge in a magnetic field maximum and minimum?
• What is the work done by a magnetic field on a moving charge?
