I forgot the questions.
What is the magnitude of F⃗ elec?
What is the tension in the string?
In an electricity experiment, a 1.30g plastic ball is suspended on a 56.0cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force F⃗ elec on it, causing the ball to swing out to a 25.0∘ angle and remain there.
