Problem
A tiny ball with a mass of 0.6 g carries a charge of magnitude 8 μC. It is suspended by a thread in a downward directed electric field of intensity 300 N/C. What is the tension in the thread if the charge on the ball is positive?
a. 2.40 x 10⁻³ N b. 6.00 x 10⁻³ N c. 8.40 x 10⁻³ N
d. 6.00 x 10⁻² N e. 6.24 x 10⁻³ N
