Answer:
0.9 N
Explanation:
The electric force acting on a charge is given by:
[tex]F=qE[/tex]
where
q is the magnitude of the charge
E is the strength of the electric field
In this problem, we have
[tex]q=4.5\cdot 10^{-5}C[/tex] is the charge
[tex]E=2.0\cdot 10^4 N/C[/tex] is the strength of the electric field
Substituting into the equation, we find
[tex]F=(4.5\cdot 10^{-5}C)(2.0\cdot 10^4 N/C)=0.9 N[/tex]
