5.4 Exercise 6

Avg difficulty 2.5

A particle of charge 2.0×10−8C2.0 \times 10^{−8} \text{C} experiences an upward force of magnitude 4.0×10−6N4.0 \times 10^{−6} \text{N} when it is placed in a particular point in an electric field. (a) What is the electric field at that point? (b) If a charge q=−1.0×10−8Cq = −1.0 \times 10^{−8} \text{C} is placed there, what is the force on it?
