For the following questions answer them individually
Find the values of $$K_P, K_1 and K_D$$ for PID controller whose characteristics equation has real roots at $$10, \epsilon = 0.8 and \omega_n = 2rad/s$$
The wavelength of emitted radiation by electron while transiting from one energy state of -15eV to other energy state of -5eV is
The electric field component of a time harmonic plane EM wave traveling in a non-magnetic lossless dielectric medium has amplitude of 2V/m. If the relative permittivity of the medium is 4, the magnitude of the time-average power density vector $$(in W/m^2)$$ is
The force on a point charge +q kept at a distance d from the surface of an infinite grounded metal plate in a medium of premittivity $$\epsilon$$ is
A material has conductivity of $$10^{-2}$$ mho/m and a relative permittivity of 4. The frequency at which the conduction current in the medium is equal to the displacement current is
A system has fourteen poles and two zeros. Its high frequency asymptote in its magnitude plot having a slope of
A 1 mW video signal having a bandwidth of 100 MHz is transmitted to a receiver through a cable that has 40 dB loss. If the effective one-sided noise spectral density at the receiver is $$10^{-20}$$ Watt/Hz, then the signal-to-noise ratio at the receiver is
