## Carniel 2 years ago A beam of electrons moves at right angles to a magnetic field of 4.5 × 10^-2 tesla. If the electrons have a velocity of 6.5 × 106 meters/second, what is the force acting on the electrons? The value of q = -1.6 × 10^-19 coulombs.Select one of the options below as your answer: A. -2.9 × 106 N B. -4.9 × 10^-14 N C. -4.9 × 10^-14 N D. -6.5 × 10^-13 N

Plz help :'(

2. kausarsalley

F = Bqv sin theta F=Force B=magnetic flux density q=charge v=velocity theta=angle the moving electrons make with the magnetic field.

3. kausarsalley

do you understand it now??

4. Carniel

Not really :(

5. Carniel

Can u plz explain what I'm suppose to do to find the answer in a clear mannor. Really trying to specialize in Physics.

6. kausarsalley

you are finding the force so using that formula, |dw:1363635861462:dw|

7. kausarsalley

does that help??

8. kausarsalley

i think you made a mistake in writing the possible answer.....B and C have the same value

Thx and this is what the teacher gave us.
