In an experiment designed to measure the magnitude of a uniform magnetic field, a charge with q = -10 x 10-16 C and mass m = 10 x 10-25 kg is accelerated from rest through a potential 50000 V and then enters a uniform magnetic field that is perpendicular to the velocity of the charge. The charge travels along a curve path because of the magnetic force exerted on it, and the radius of the path is measured to be 2.50 mm. What is the magnitude of the Magnetic Field?
