Assertion : Size of nucleus is constant in electron scattering or gamma scattering.

Reason : Electron scattering or gamma scattering is controlled by distribution of charge in
nucleus.

View answer and explanation

Correct option: C

If Assertion is True but the reason is false

Option C (If Assertion is True but the reason is false) is correct because the size of the nucleus remains constant during scattering experiments, but the scattering is controlled by the distribution of charge AND matter in the nucleus, not just charge.
