In electrostatic field $$\nabla\times\overrightarrow E\equiv0$$

Static magnetic fields induce currents in closed conducting loops.

Match the following List-$${\rm I}$$ with List-$${\rm II}$$

List $$-$$ $${\rm I}$$
$$(a)$$ Line charge

$$(c)$$ Displacement current
$$(d)$$ Power flow

List $$-$$ $${\rm II}$$
$$(P)$$ Maxwell's
$$(Q)$$ Poynting vector
$$(R)$$ Transmission line conductors
$$(S)$$ Biot-Savart's law
$$(T)$$Gauss's law
$$(U)$$ Faraday's law

The eigen values of the matrix $$\left[ {\matrix{ a & 1 \cr a & 1 \cr } } \right]$$ are
