Acharged particle of mass 153 g is moving at a speed of 1.58x 10 m/s suddenly, a uniform magnetic field of magnitude 0.157 mt in a direction perpendicular to the particle's velodity is turned on and then turned off in a time interval of 1.00s. during this time interval, the magnitude and direction of the velocity of the particle undergo a negligible change, but the particle moves by a distance of 0.150 m in a direction perpendicular to the velocity. find the charge on the particle
