Question

A negatively charged glass rod is brought near a neutral table tennis ball. What will happen to the neutral table tennis ball?

A. The table tennis ball will become positively charged.
B. The table tennis ball will become negatively charged.
C. The table tennis ball will not be affected by the glass rod.
D. The table tennis ball will become polarized, with positive charges toward the glass rod.
E. The table tennis ball will become polarized, with negative charges toward the glass rod

Answer 1

First off, this question depends on if a table tennis ball is an insulator....which I ask you? Is it? Haha

Answer 2

I have no idea .. lol. This is for my online physics class. Thats all the question says o:

Answer 3

I think its B?

Answer 4

Well let's assume that it IS not an insulator, because insulators are objects such as rubber and stuff. So you have a charged object being brought near a neutral one. TO THE DIAGRAMS
Now as the rod get's closer it's going to pull the positive charges of the ball toward it and push away the negative (because neg and positive attract and neg and neg repel) so we get this

So this is called POLARIZATION, when you seperate the positive and negative charges of an object. Now, you have polarized the teenis ball and brought the positive charges close to the rod, and the negative charges away!
This situation sounds alot like choice D to me.
