Give similarity between Biot-Savart law and electrostatic law of Coulomb.

(N/A) The Biot-Savart law for the magnetic field $dB$ due to a current element $Idl$ is given by $dB = \frac{\mu_0}{4\pi} \frac{I dl \sin \theta}{r^2}$.
The Coulomb's law for the electric field $dE$ due to a point charge $dq$ is given by $dE = \frac{1}{4\pi \epsilon_0} \frac{dq}{r^2}$.
Similarities:
$1$. Both laws are long-range laws,as they both depend on the inverse square of the distance $(1/r^2)$ from the source.
$2$. Both laws follow the principle of superposition.
$3$. Both laws are linear with respect to their sources (current element $Idl$ for magnetic field and charge $dq$ for electric field).
