The major product in the following reaction is:

$A$ resistor of $2 \Omega$,an inductor of $100 \mu H$,and a capacitor of $400 pF$ are connected in series across a source of $e_{rms} = 0.1 \text{ V}$. At resonance,the voltage drop across the inductor is: (in $\text{ V}$)

$A$ block of $200 \text{ g}$ mass moves with a uniform speed in a horizontal circular groove with vertical side walls of radius $20 \text{ cm}$. If the block takes $40 \text{ s}$ to complete one round,the normal force exerted by the side walls of the groove is:

The work function of a certain metal is $3.31 \times 10^{-19} \, J$. The maximum kinetic energy of photoelectrons emitted by incident radiation of wavelength $5000 \, \text{Å}$ is: (Given: $h = 6.62 \times 10^{-34} \, J \cdot s$, $c = 3 \times 10^8 \, m/s$, $e = 1.6 \times 10^{-19} \, C$) (in $\text{eV}$)
