An inductor and a resistor are connected in series to an $AC$ source. The current in circuit is $500\, mA$, if the applied $AC$ voltage is $8 \sqrt{2} V$ at a frequency of $\frac{175}{\pi} Hz$ and the current in the circuit is $400\, mA$, if the same $AC$ voltage at a frequency of $\frac{225}{\pi} Hz$ is applied. The values of the inductance and the resistance are respectively

A uniform chain of mass $m$ and length $l$ is on a smooth horizontal table with $\left( \frac{1}{n}\right)^{th}$ part of its length is hanging from one end of the table. The velocity of the chain when it completely slips off the table is

Water stands upto height $h$ behind the dam as shown in the figure. The front view of the dam gate is also shown in the adjoining figure. Density of water is $\rho$ and acceleration due to gravity is $g$. If atmospheric pressure force is also considered, then the point of application of total force acting on the dam due to water above $O$ is
