I really don't understand the answers to these questions. Can I please get a detailed explanation?
This problem explores the behavior of charge on conductors. We take as an example a long conducting Part A rod suspended by insulating strings. Assume that the A small metal ball is given a negative charge, then brought near e., within about 1/10 the length of the rod) to end A of the rod (Figure 1) rod is initially electrically neutral. For convenience we What happens to end A of the rod when the ball approaches it closely this first time? will refer to the left end of the rod as end A, and the right end of the rod as end B. In the answer options for this problem, "strongly a means It is strongly repelled. "attracted repelled with a force of magnitude similar to that which would exist between two charged balls. is strongly attracted It is weakly attracted. Figure 1 of 1 It is weakly repelled. It is neither attracted nor repelled Submit Hints My Answers Give Up Review Part Correct This charge is said to be "induced" by the presence of the electric field of the charged ball: It is not transferred by the ball. Now consider what happens when the small metal ball is repeatedy given a negative charge and then brought into contact with end A of the rod,Explanation / Answer
a )
it is strongly attracted
b )
there is negatoive charge spread evenly on both sides of the ends
c )
it is repelled strongly
d )
it is repelled strongly
