$A$ flywheel is in the form of a solid circular disc of mass $72 \, kg$ and radius $0.5 \, m$. If it rotates at $70 \, r.p.m.$,then the rotational kinetic energy is approximately ....... $J$.

The network shown in the figure is a part of a complete circuit. If at a certain instant the current $i$ is $5 \ A$ and is decreasing at the rate of $10^3 \ A/s$,then $V_A - V_B$ is ..... $V$.

Hydrolysis of sucrose with dilute aqueous sulphuric acid yields

Along the $X$-axis,three charges $\frac{q}{2}, -q$ and $\frac{q}{2}$ are placed at $x=0, x=a$ and $x=2a$ respectively. The resultant electric potential at $x=a+r$ (if $a \ll r$) is: ($\varepsilon_0$ is the permittivity of free space)
