Answer #1

As Ball 3 is negative and it repels ball 2, so, ball 2 must be of same polarity as ball 3, as we know that two same polarity charges repel each other. Thus ball 2 is also negatively charged. Again ball 2 attracts ball 1 and as attraction happens between two opposite polarity charges, so, ball 1 must be positively charged.

One additional observation could be made about ball 3 and ball 1. Since they are oppositely charged (one positive and other negative), so balls 1 and 3 will attract each other.

Pith balls are small, lightweight objects that can pick up an electric charge. Suppose an experiment is performed and results show that Ball 1 attracts Ball 2. A third ball, Ball 3, is negative and repels Ball 2. What can be concluded about Ball 1 in terms of a charge sign and its value? Assign any charge to Ball 2 and Ball 3 as well as assign distances between all the charges. Assume that they lie on one the same...

A 1-kg ball is released from a height of 6 m, and a 2-kg ball is released from a height of 3 m. Air resistance is negligible as they fall. Which of the following statements about these balls are correct? (There could be more than one correct choice.) Both balls will reach the ground with the same speed. As they reach the ground, the 1-kg ball will have more kinetic energy than the 2-kg ball because it was dropped from...

3. Consider the following game. A bucket contains one black ball and n − 1 white balls. Two players take it in turn to draw balls from the bucket. On each turn, a player draws a ball from the bucket. If the player draws the black ball, then that player wins and the game ends. If the player draws a white ball, then the ball is returned to the bucket and the game continues until one player draws the black...

Three Styrofoam balls are suspended from thin threads. Various objects are then rubbed against each other (wool against plastic, silk against glass, etc...) and each Styrofoam ball is charged by toughing. It is found that balls 1 and 2 repel each other and that balls 2 and 3 attract each other. From this we can conclude (check all that apply). 2 and 3 carry charges of the same sign we need more information to determine the sign of the net...
