A small 1.10-gram hollow metal ball is on the end of a plastic rod, while an identical hollow metal ball is suspended from a 12.0-cm string. The ball on the rod is given an electric charge and then touched to the suspended ball, as shown.

     When the ball on the rod is 8.0 horizontal centimeters away from the suspended ball, the string holding the suspended ball makes a 30º angle with the horizontal, as shown.

     Determine the amount of charge on each of the two balls.

    In an electricity experiment, a 1.10 g plastic ball is suspended on a 60.0 cm 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 23.0 ∘ angle and remain there. What is the tension in the string?

    a) You're holding a small metal ball suspended on a piece of insulating string from the ceiling. You and the ball are both initially electrically neutral. A positively charged rod is brought near to the metal ball; you then let go of the metal ball. You now have a positive electric charge. This process is called charging by 1.) Electroscope. 2.) Insulation. 3.) Conduction. 4.) Induction. b) Charged glass and plastic rods hang by threads. An object attracts the glass...
