A charge of -8.9 C is traveling at a speed of 7.8 106 m/s in a region of space where there is a magnetic field. The angle between the velocity of the charge and the field is 60. A force of magnitude 4.0 10-3 N acts on the charge. What is the magnitude of the magnetic field?

HI! Can you guide to which equation to use for this problem: An electron with the speed of 2 x 10^7 m/s enters a magnetic field with a velocity vector 25^0 away from the magnetic field direction. If it experiences an acceleration of 1.5 x 10^16 m/s^2, determine (absolute value...
