Question

Assertion (A): The force of repulsion between atomic nucleus and α-particle varies with distance according to inverse square law.

Reason (R): Rutherford did α-particles scattering experiment.

विकल्प

• Both (A) and (R) are true, and (R) is the correct explanation of (A).

• Both (A) and (R) are true, but (R) is not the correct explanation of (A).

• (A) is true, but (R) is false.

• Both (A) and (R) are false.

Answer 1

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

Explanation:

Rutherford confirmed the repulsive force on α-particle due to nucleus varies with distance according to inverse square law (F ∝ 1/r²), Both assertion and reason are true but reason is not the correct explanation of assertion.
