Directions: These questions consist of two statements, each printed as...
Explanation: The Assertion is incorrect because, according to classical theory, the proposed path of an electron in the Rutherford atom model would not be parabolic; it would be elliptical or circular. The model predicted that electrons orbit the nucleus much like planets orbiting the sun, which would lead to closed orbits, not open parabolic paths.
The Reason is correct in stating that according to classical electromagnetic theory, an accelerated charged particle emits radiation. However, this emission of radiation would cause the electron to lose energy and spiral into the nucleus rather than follow a parabolic path. This was one of the key issues with the Rutherford model, as it could not explain the stability of atoms, since classical mechanics would predict that electrons should crash into the nucleus rather than staying in a stable orbit.

Explanation:
Assertion:
According to classical theory the proposed path of an electron in Rutherford atom model will be parabolic.
Reason:
According to electromagnetic theory an accelerated particle continuously emits radiation.
- Correct Answer: Option D
Explanation:
1. The assertion states that according to the classical theory, the proposed path of an electron in the Rutherford atom model will be parabolic. This is a correct statement based on the Rutherford model, which describes the atom as a dense positively charged nucleus with electrons orbiting around it in fixed paths.
2. The reason given is that according to electromagnetic theory, an accelerated particle continuously emits radiation. This is also a correct statement based on electromagnetic theory, where an accelerating charged particle will emit electromagnetic radiation.
3. However, the reason is not a correct explanation of the assertion. In the Rutherford model, the electron's path is not parabolic due to the emission of radiation. The emission of radiation by an accelerated electron would cause it to lose energy and spiral into the nucleus, which contradicts the stable orbit concept of the Rutherford model.
4. Therefore, the correct answer is option D, where the assertion is incorrect (as the electron's path is not parabolic in the Rutherford model) but the reason is correct (as an accelerated particle does emit radiation according to electromagnetic theory).
