Answer:
[tex]q = 1.15 C[/tex]
Explanation:
Force on a charge particle due to external electric field is given as
[tex]F = qE[/tex]
now we know that acceleration is defined as the ratio of force and mass
[tex]a = \frac{F}{m}[/tex]
now we have
[tex]a = \frac{qE}{m}[/tex]
[tex]a = 13 m/s^2[/tex]
[tex]m = 441 g = 0.441 kg[/tex]
[tex]E = 5 N/C[/tex]
now we have
[tex]13 = \frac{q(5)}{0.441}[/tex]
[tex]q = 1.15 C[/tex]
