Assertion: The force of repulsion between atomic nucleus and `alpha`-p

1.	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.A. If both assertion and reason are true and reason is the correct explanation of assertion.B. If both assertion and reason are true but reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If assertion is false but reason is true.
Answer» Correct Answer - B Rutherford confirmed the repulsive force on `alpha`-particle due to nucleus varies with distance according to inverse square law and that the positive changes are concentraed at the cnetre and not distributed throughout the atom.
