Question

ANALYSIS Part I Demonstrations with the electroscope 1. For each step 1 through 4, sketch the conducting parts of the electroscope and the nearby rod, and show the distribution of charges on each. 2. Explain your observations for steps 1 through 5. Part II Forces that charged objects exert on each other 3. What force, attraction or repulsion, do charges having the same sign exert on each other? 4. What force, attraction or repulsion, do charges having opposite signs exert on each other? 5. How do you explain your observations in steps 9 and 10? Part IlI Determining the sign of a charge with a Faraday pail 6. What were the signs of the charge for the gray and white charge separators? 7. What was the net charge on the pair of separators?

Answer 1

3.

we know that like charge repel each other and unlike charges attract each other. hence charges having same sign exert force of repulsion on each other.

4.

we know that like charge repel each other and unlike charges attract each other. hence charges having opposite sign exert force of attraction on each other.
