Answer:
a. 8000 N/C or 8000 V/m
b. Incomplete question
Step-by-step explanation:
a. The electric field, E, is the ratio of the potential difference,V, to the separation distance, d.
V = 360 V
d = 45 mm = 0.045 m
b. The force on a charge in an electric field is the product of the field and the charge.
With the charge, q, known, the force can be calculated.
