Question

There are two bodies A and B. 'A' has a negative charge whereas 'B' has no charge. When A and B are connected by a metallic wire, in what direction will the electrons flow?

• A. Electrons flow in random directions and will effectively move from A to B
• B. Electrons flow in random directions and will effectively move from B to A
• C. Electrons flow in random directions and will effectively stay in the same position
• D. Electrons won't move in any direction

Answer 1

The correct option is A

Electrons flow in random directions and will effectively move from A to B

In a conductor, the electrons always move in random directions. When there is a difference in potential, the electrons will effectively move from a region of lower potential to a region of higher potential.

Here, the negatively charged body A is said to be at a lower potential than the uncharged body B. There is a difference in potential. Hence, electrons will flow from the negatively charged body A to the uncharged body B.
