A Barium Titanite Pick-up has the dimensions of $5\ \mathrm{mm} \times 5\ \mathrm{mm} \times 1.25\ \mathrm{mm}$. The force acting upon it is $5\ \mathrm{N}$. The charge sensitivity of it is $150\ \mathrm{pC/N}$ and its permittivity is $12.5 \times 10^{-9}\ \mathrm{F/m}$. If the modulus of elasticity of it is $12 \times 10^{6}\ \mathrm{N/m^{2}}$, calculate the strain. Also calculate the charge and the capacitance.
