What is the electric field strength at the position of the proton in the figure?(Figure 1) Assume that B = 0.10 T and F = 3.4×10−13N .

Honestly I don't know. Since we have a velocity, b-field, and force i thought F=qvXb but that doesn't help with solving the electric field. Other than that I really don't know.
The Attempt at a Solution
I really haven't even been able to start. I have no idea how to approach the problem.
