Question
Find the dimensions of:
- Linear momentum.
- Frequency.
- Pressure.
✓
Answer
- Linear momentum: $\text{mv}=[\text{MLT}^{-1}]$
- Frequency: $\frac{1}{\text{T}}=[\text{M}^0\text{L}^0\text{T}^{-1}]$
- Pressure: $\frac{\text{Force}}{\text{Area}}=\frac{[\text{MLT}^{-2}]}{\text{[L}^2]}=[\text{ML}^{-1}\text{T}^{-2}]$

A hydrogen atom contains one proton and one electron. It may be assumed that the electron revolves in a circle of radius 0.53 angstrom (1 angstrom $= 10^{-10}m$ and is abbreviated as A) with the proton at the centre. The hydrogen atom is said to be in the ground state in this case. Find the magnitude of the electric force between the proton and the electron of a hydrogen atom in its ground state.

→The space between the plates of a parallel plate capacitor is completely filled in two ways. In the first case, it is filled with a slab of dielectric constant K. In the second case, it is filled with two slabs of equal thickness and dielectric constants $\mathrm{K}_1$ and $\mathrm{K}_2$ respectively as shown in the figure. The capacitance of the capacitor is same in the two cases. Obtain the relationship between $\mathrm{K}, \mathrm{K}_1$ and $\mathrm{K}_2$.
