Assertion: The force of repulsion between atomic nucleus and `alpha`-particle varies with distance according to inverse square law.
Reason: Rutherford did `alpha`-particles scattering experiment.

Options

A. If both assertion and reason are true and the reason is the correct explanation of the assertion.
B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false.
D. If the assertion and reason both are false

Answer

B

Explanation

Rutherford confirmed that the repulsive force on αparticle due to nucleus varies with distance according to inverse square law and the positive charges are concentrated at the centre and not distributed throughout the atom
