A glass marble is rubbed against a piece of silk. As a result, the fabric acquired extra electrons. What happens to the glass marble? 

 

The marble has lost the same number of electrons acquired by the piece of silk

The marble has acquired the same number of electrons acquired by the piece of silk

The marble acquires a positive charge and repels the piece of silk.

The marble acquires a positive charge and attracts the piece of silk.

The marble acquires a negative charge and attracts the piece of silk.

The marble acquires a negative charge and repels the piece of silk. 

After an initially neutral glass rod is rubbed with an initially neutral silk scarf, the rod a charge of . Estimate the fractional increase or decrease in the scarfs mass. (Assume the scarf had a mass of 100 g.) ΔΜ/M  would this change in mass be easily noticed? (Assume that this change is noticeable if it is more than 1 mg.)

Yes

No 

Consider 4 lightweight metal-coated balls suspended on nonconducting threads. Suppose ball A is stroked with a plastic rod that has been rubbed with fur. When you observe interactions between pairs of balls one at a time you find that:

1. B, C, and D are each attracted to A.
2. B and D seem to have no effect on each other.
3. B is attracted to C.

Use the concept of induction to figure out what type of net charge is on each of the balls: Negative charge? Positive charge?No charge at all? Explain your reasoning.
