ANSWER
[tex]7.65\cdot10^7N\/C[/tex]EXPLANATION
We want to find the magnitude of the electric field.
To do this, we have to apply the formula for electric field:
[tex]E=\frac{F}{q}[/tex]where F = force exerted on the charged particle
q = electric charge on the particle
Hence, the magnitude of the electric field is:
[tex]\begin{gathered} E=\frac{2.60}{3.40\cdot10^{-8}} \\ E=7.65\cdot10^7N\/C \end{gathered}[/tex]The correct answer is the first option.
