The correct answer is:
$\frac{\mu_0 N i R^2}{2\left(R^2+x^2\right)^{3 / 2}}$
From the formula, magnetic field intensity at point $P$, shown in given figure while coil carry current $i$ and having $N$ turns is given by
$\frac{\mu_0 N i R^2}{2\left(R^2+x^2\right)^{3 / 2}}$
$\frac{\mu_0 N i R^2}{2\left(R^2+x^2\right)^{3 / 2}}$
