The path of a charged particle in a uniform magnetic field depends on the angle theta between velocity vector and magnetic field, When theta is 0^(@) or 180^(@), F_(m) = 0 hence path of a charged particle will be linear. When theta = 90^(@) , the magnetic force is perpendicular to velocity at every instant. Hence path is a circle of radius r = (mv)/(qB) . The time period for circular path will be T = (2pim)/(qB) When theta is other than 0^(@), 180^(@) and 90^(@) , velocity can be resolved into two components, one along vec(B) and perpendicular to B. v_(|/|)=cos theta v_(^)= v sin theta The v_(_|_) component gives circular path and v_(|/|) givestraingt line path. The resultant path is a helical path. The radius of helical path r=(mv sin theta)/(qB) ich of helix is defined as P=v_(|/|)T P=(2 i mv cos theta) p=(2 pi mv cos theta)/(qB) Which particle will have minimum frequency of revolution when projected with the same velocity perpendicular to a magnetic field.

Statement-1 A charged particle when projected perpendiculary to a uniform magnetic field, its velocity is constant through out its motion Statement-2 A charged particle its acceleration is zero Statement-3 A charged particle when projected perpendicular to a uniform magnetic field, a magnetic force acts on it but that does not change particle's speed

A proton moves at a speed v = 2xx10^(6) m//s in a region of constant magnetic field of magnitude B = 0.05 T. The direction of the proton when it enters this field is theta = 30^(@) to the field. When you look along the direction of the magnetic field, then the path is a circle projected on a plane perpendicular to the magnetic field. How far will the proton move along the direction of B when two projected circles have been completed?
