A particle has a charge of 5.2 × 10-19 coulombs and experiences a force of
9.5 × 10-15 newtons when it travels through a magnetic field with strength
2.2 × 10-1 tesla. What is the speed of the particle? this is a physics question so yall better not tell me to move my post again!

Is that the complete question ?

ganeshie8 · Answer

I think we need to also know the angle between "velocity" and "magnetic field"

yes that is the complete question it has nothing else on it.

irishboy123 · Answer

use the lorentz force law

irishboy123 · Answer

really good thing to know:

$$\mathbf{F} = q\left[\mathbf{E} + (\mathbf{v} \times \mathbf{B})\right]$$

anonymous · Answer

@IrishBoy123 Just curious, but what would be substituted for $\mathbf{E}$?

Also, I agree with @ganeshie8. I believe that some sort of angle is required to figure out the rest.

@CShrix
i guessed that it has to be moving in a circle.....and E = 0 as no E field is mentioned.

but, yes, that's an assumption.  it could be moving in a helix or otherwise not totally $\perp$ to field......
