An electron moving at $4.00 \times 10^{3} \mathrm{m} / \mathrm{s}$ in a $1.25-\mathrm{T}$ magnetic field experiences a magnetic force of $1.40 \times 10^{-16} \mathrm{N} .$ What angle does the velocity of the electron make with the magnetic field? There are two answers.

The angle between the electron velocity and the magnetic field is $10.1^{\circ}$ or $169.9^{\circ} .$

force f is gonna be equaling to the charge multiplied by the velocity times the magnitude of the magnetic field multiplied by sine of Fada. We can then say that they would be equaling Arc signed of theme magnitude of the magnetic force divided by the charge times. The velocity times be the magnitude of the magnetic field weakened. Then solve this would be arc sine Ah, this would be 1.40 times 10 to the negative 16th Newtons, divided by the charge of an electron 1.60 times 10 to the negative 19th. Cool arms multiplied by the velocity of 4000 four times 10 to the third. Or we can say 4000 meters per second multiplied by 1.25 Tesla's and we can then find that Fada, which in this case would be the angle between the between the electrons velocity and the magnetic field. This would be either 10.1 degrees or we can say it's supplement angle 169.9 degrees. These would be our two answers. That is the end of the solution. Thank you for launch
