(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In an electricity experiment, a 1.30 g plastic ball is suspended on a 54.0 cm long string and given an electric charge. A charged rod brought near the ball exerts a horizontal electrical force vector F elec on it, causing the ball to swing out to a 21.0 angle and remain there.

1.) What is the magnitude of vector F?

2.)What is the tension in the string?

Any help would be appreciated!

3. The attempt at a solution

I honestly have no idea how to start it. A step by step on how to solve it would be nice but any help is appreciated.
