(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A force of 2.4N is exerted on a -1.8µC charge in a downward direction. What is the magnitude and direction of the magnetic field at this point?

(The assignment sheet is called "Electrostatics Questions", hence the "Electrostatics?" in the title)

2. Relevant equations

Electric Field Intensity Vector:

ε = F/q

Pertaining to Magnetic Fields:

F = qvBsinθ

B = µ_{o}I / Δl

3. The attempt at a solution

I was just wondering how I should tackle this question. The title of the assignment sheet is Electrostatics questions and at this point we had not yet studied magnetic fields. Does the electric field formula apply to this equation or how should I proceed with the question?

If the question can be solved with the electric field equations, I'll be able to solve it, as it is simple math. I just need help in understanding which equation to use here.

If the question should be solved with Magnetic Field equations, is the "magnitude and direction of the magnetic field" that the question asks for the value of B (Field strength)? The question also seems to be missing some values if trying to solve via the magnetic field equations?

Thanks for any help!
