Question

Rutherford’s model of atom resembles the solar system in which the nucleus plays the role of sun and the electrons that of revolving planets but it could not explain the stability of atom because

• A. Gravitational force is weeker than electrostatic force
• B. Gravitational force is stronger than electrostatic force
• C. The palnets revolving around the sun carries net charge
• D. Electrons revolving around nucleus carries net charge

Answer 1

The correct option is D Electrons revolving around nucleus carries net charge

Planets revolving around the sun are assumed to be neutral, while electron carries a net negative charge.
An accelarated charged body emits radiation thus loses energy hence an electron revolving around nucleus will lose energy and eventually will fall into nucleus following spiral path.
