Assume a charged object with a mass of 3.6 gram moves in the positive direction of the z- axis with a kinetic energy of 18 kj. This object enters in a region of magnetic field of 7.2 mT whose direction is in in the positive y-axis. If the magnetic force act on it is 8.4 µN in the positive x-axis, calculate the sign and the magnitude of the charge. Select one: a. 7.7x10 C, the sign is negative b. 7.7x10 C, the sign is positive c. 3.7x10 C, the sign is negative -7 d. 3.7x10 C, the sign is positive Assume a charged object with a mass of 3.6 gram moves in the positive direction of the z- axis with a kinetic energy of 18 kj.
