Answer:
(a). The electric force is 0.9 N.
(b). The acceleration is 0.9 m/s²
Explanation:
Given that,
Mass = 1.0 kg
Distance = 1.0 m
Charge = 10 μC
(a). We need to calculate the electric force
Using formula of electric force

Put the value into the formula


(b). We need to calculate the acceleration
Using newton's second law


Put the value into the formula


Hence, (a). The electric force is 0.9 N.
(b). The acceleration is 0.9 m/s²
