QUESTION 7 A charge q = +1.60E-12 C moves with speed 4.32E4 m/s through a constant magnetic field of strength 5.65 T. The charge's velocity vector makes an angle of 42.10 with the direction of the magnetic field. What is the magnetic force exerted on the charge (in Newtons (N))? QUESTION 8 An EM wave with wavelength 6.50E-7 m passes through a thin slit and form a diffraction pattern on a screen 5.51 m away. The distance between the central bright fringe and the first dark fringe is measured to be 4.20E-3 m. What is the slit width (in meter)
