Choose the correct option for the following Assertion (A) and Reason (R).

Question

G1 Physics · Accepted Answer

In Rutherford's planetary picture, an electron moving around the nucleus has centripetal acceleration. Classical electrodynamics predicts that an accelerated charge radiates energy. Therefore the electron should continuously lose mechanical energy, its orbit should shrink, and it should eventually fall into the nucleus. Real atoms are stable, so the classical Rutherford model could not explain atomic stability. Both Assertion and Reason are true, and the Reason correctly explains the Assertion.…
