Rutherford and Bohr models
Why this is asked: Rutherford's model correctly located the nucleus but couldn't explain atomic stability — classically an accelerating orbiting electron should radiate energy and spiral inward. Bohr fixed exactly this by allowing only orbits with quantised angular momentum, L = nh/2π.

- •A particle of mass is moving around the origin with a constant force pulling it towards the origin. If the Bohr model is used to describe its motion, the radius of the th orbit and the particle's speed in the orbit depend on as:
- •Given below are two statements: Statement I: Atoms are electrically neutral as they contain equal number of positive and negative charges. Statement II: Atoms of each element are stable and emit their characteristic spectrum. In the light of the above statements, choose the most appropriate answer from the options given below:
