this is a nice problem. of magnetism.............there is a particle of mass 'm'.....initially located at the origine........a uniform magnetic field Bi is present in space.......the partical is given an initial velocity of vxi + vyj...............find the limiting value of 'B' for which the particle hits an obstacle present at the pt (x,0)..........accha prob. hai..ull enjoy it if u are doing it for the first time...........none the less keeps giving u pleasure evry time u do such probs.......
