Question

using bohr's theory ,derive an expression for b) p.e ​

Answer 1

Answer:

Using Bohr's postulates of the atomic model, derive the expression for radius of nth electron orbit. Hence obtain the expression for Bohr's radius.

Centripetal force is provided by the electrostatic force of attraction.

rmv2=4πεor2e2

From bohr's second postulate.

Ln=mvnrn=2πnh

Eliminating vn from above equations.

rn=πme2n2h2εo

Bohr's radius is the radius of the innermost orbit. Hence, n=1

r1=πme2h2εo
