The magnitude of the electric field is 
Explanation:
The electrostatic force experienced by an electric charge immersed in an electric field is given by

where:
q is the charge of the particle
E is the strength of the electric field
F is the force
In this problem, we have:
is the charge of the particle
is the force
Therefore, we can find the electric field by solving the equation for E:
