Bohr S Model For Hydrogen Atom

Radius of orbit in an atom,

So,
Given in question, difference between radii of and orbit = radius of orbit.

or
According to Bohr's postulate, angular momentum is an integral multiple of .
So, for orbit,

Step 1: Write the Reaction Step 2: Apply Equilibrium Expression Solving:

Step 1: Dissociation of Barium Phosphate The chemical formula of barium phosphate is: It dissociates as: Step 2: Express Ion Concentrations in Terms of
- The solubility is g per 100 mL.
- The molar solubility is .
From the dissociation:
-
- Step 3: Write the Solubility Product Expression Step 4: Compare with the Given Equation Thus, we get:

Step 1: Apply Bohr Radius Formula For a hydrogen-like ion: For ( ): Step 2: Compute the Difference Thus, the correct answer is m.
