A) a current will flow from A to B
B) there will be no current in the wire
C) a current will flow from B task q
D) a current will flow from each end to the midpoint of the wire
Correct Answer: A
Solution :
When\[\alpha \text{-}\]particles fall on end A, it will become positive and when\[\beta \text{-}\]particles (i.e., electrons) fall on end B, it will become negative. That is, end A is at higher potential and end B is at lower potential. So, a current will flow from end A to end B to equalize the potential at two ends.
