An electron after being accelerated through a potential difference of 10^{4} _{ }Volt enters a uniform magnetic field of 0.04T perpendicular to its direction of motion.Calculate the radius of curvature of its trejectory?

The method proposed by kushal1122 is correct. One obtains a formula for radius of the path,

r =

=> r = 8.43 X 10^{-3} m

@ kushal: Good work! keep posting!
