Question

Assertion : Electrons move away from a region of lower potential to a region of higher potential.
Reason : Since an electron has a negative charge.

• A. If both Assertion and Reason are true, and Reason is a correct explanation of the Assertion
• B. If both Assertion and Reason are true, but Reason is not a correct explanation of the Assertion
• C. If Assertion is true, but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (A)

Suppose $A$ and $B$ are two regions having potcntials $V_1$ and $V_2$ such that $V_1>V_2$. So the clectric field will be set up from $A$ to $B$ (i.e. from higher potential to lower potential). Now since the electron has got a negative charge, the force experienced by the electron will be in a direction opposite to the direction of the electric field. Hence the electrons move from a region of lower potential to a region of higher potential due to their negative charges.
