In an electricity experiment, a 1.0 g plastic ball is suspended on a 60 cm long string
Question:
In an electricity experiment, a 1.0 g plastic ball is suspended on a 60 cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force F(vector)elec on it, causing the ball to swing out to a 20° angle and remain there.
a. What is the magnitude of F(vector)elec?
b. What is the tension in the string?
