Question

an electron travels at 0.3037 times the speed of light through a magnetic field and feels a force of 1.2498 pN. What is the magnetic field in teslas

Answer 1

Step-by-step explanation:

Charge on an electron (q) = 1.6 * 10 ^ -19 C

Velocity of electron (v) = 0.3037 * 300,000,000 = 91,110,000 m/sec

We know that, Force exerted on moving particle moving through a magnetic field :

`F= q * v * B ( q,v\ and\ B\ are\ mutually\ perpendicular)`

1.2498 * 10 ^ -12 = 1.6 * 10^ -19 * 91110000 * B

B = 0.08573 T
