Chapter 6, Problem 29P(choose chapter or problem)
In an electricity experiment, a \(1.0 \mathrm{~g}\) plastic ball is suspended on a \(60-\mathrm{cm}\)-long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force \(\vec{F}_{\text {elec }}\) on it, causing the ball to swing out to a \(20^{\circ}\) angle and remain there.
a. What is the magnitude of \(\vec{F}_{\text {elec }}\)?
b. What is the tension in the string?
