A uniform magnetic field is directed in the +z or -z direction. A charge of -3 Coulombs with a mass of 7 kg is initially moving in the +x direction at 11 m/s. Due to the magnetic field, it moves in a circle with a radius of 2 meters counter-clockwise. What is the magnitude and the direction of the magnetic field in Tesla? Indicated the negative z direction by including a negative sign, but don't include a sign for the +z direction.
