A certain particle having an unknown positive charge and an unknown mass was released from rest from the origin of a co-ordinate axis.The particle is subjected to a simultaneous action of a magnetic field B 0 k(cap) and an electric field E 0 j(cap).During the subsequent motion of the particle it was found that its maximum y-coordinate is y 0 and radius of curvature of its trajectory at the maximum y-coordinate is R.Both E 0 and B 0 are positive quantities.Find the speed of the particle when its y co-ordinate is y 0. ans is E 0 /B 0 (1+2y 0 /R)
