Answer:
0.027 J
Explanation:
The formula of the potential energy in electrostatic (U) is
[tex]U = q \times E \times d[/tex]
The values given in the question are
Charge : q = [tex]4.5 \times 10^{-5} C[/tex]
Electric Field strength : E = [tex]2.0 \times 10^{4} N/C[/tex]
Distance : d is 0.030 m
Insert in the formula , will give us
[tex]U = 4.5 \times 10^{-5} C \times 2.0 \times 10^{4} N/C \times 0.030 m[/tex]
Further solving it
[tex]U = 0.027 J[/tex]
Which is the required answer.
