An electron in a television CRT moves toward the front of the tube with a speed of 7.5x10^6 m/s. A magnetic field of 0.04T (on a 50 degrees angle) causes the electrons to accelerate. Determine the acceleration

Answer 1

F=ma=evBsinα
a= evBsinα/m =1.6•10⁻¹⁹•7.5•10⁶•0.04•sin50/9.1•10⁻³¹= 4•10¹⁶ m/s²
