Question
For two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below:
  1. Both A and R are true, and R is correct explanation of the assertion.
  2. Both A and R are true, but R is not the correct explanation of the assertion.
  3. A is true, but R is false.
  4. A is false, but R is true.
Assertion: Electron has a negative charge.
Reason: Electrons move always from a region of higher potential to a region of lower potential.

Answer

  1. A is true, but R is false.

Explanation:



Suppose A and B are two regions having potentials V1 and V2 such that V1 > V2 So the electric current will flow from A to B (i.e., from higher potential to lower potential). Since electrons move opposite to the direction of current, hence, the electrons move from a region of lower potential to a region of higher potential.
