A hypothetical charge of 60 pC with a mass of 48 fg has a speed of 77 km/s and is ejected southward entering a uniform magnetic field of unknown magnitude and direction. If the path traced is clockwise, Find the magnitude and direction of the magnetic field that will cause the charge to follow a semicircular path (given the diameter 47 m). Find the time required for the charge to complete a semi-circular path from point K to point L. Find the magnitude and the direction of the magnetic force at point L.
