A particle of mass 5.7 x 10 kg and charge +8.9 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 4.1 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number Units
