Answer:
[tex]4.26*10^6N[/tex]
Explanation:
A charge within an electric field E experiences a force proportional to the field whose module is F = qE, whose direction is the same, if the charge is negative, it experiences a force in the opposite direction to the field and if the charge is positive, experience a force in the same direction of the field.
In our case we are interested in the magnitude of the force, therefore the sign of the charge has no relevance
[tex]\left | F \right |=\left |q \right | \left |E\right |\\\left | F \right |=6.00C*710000\frac{N}{C}=4.26*10^6N[/tex]
