A strain gauge is attached on a cantilever beam as shown. If the base of the cantilever vibrates according to the equation $x(t)=\sin\omega_1t+\sin\omega_2t,$ where $2\;\text{rad/s}<\omega_1,\;\omega_2<3\;\text{rad/s},$ then the output of the strain gauge is proportional to $x$ $\frac{dx}{dt}$ $\frac{d^2x}{dt^2}$ $\frac{d(x-y)}{dt}$

A coil having an impedance of (10 + j100) $\Omega$ is connected in parallel to a variable capacitor as shown in figure. Keeping the excitation frequency unchanged, the value of the capacitor is changed so that parallel resonance occurs. The impedance across terminals p-q at resonance (in $\Omega$) is $\_\_\_\_$.

The voltage and current drawn by a resistive load are measured with a $300\; V$ voltmeter of accuracy $\pm1\%$ of full scale and a $5 \;A$ ammeter of accuracy $\pm 0.5\%$ of full scale. The readings obtained are $200\; V$ and $2.5\; A$. The limiting error (in $\%$) in computing the load resistance is (up two decimal places) $\_\_\_\_\_\_\_$.
