A circular coil of radius '$$r$$' and number of turns ' $n$ ' carries a current '$$I$$'. The magnetic fields at a small distance '$$h$$' along the axis of the coil $$\left(B_a\right)$$ and at the centre of the coil $$\left(\mathrm{B}_{\mathrm{c}}\right)$$ are measured. The relation between $$B_c$$ and $$B_a$$ is

$$\mathrm{B_c=B_a\left(1+\frac{h^2}{r^2}\right)}$$

$$\mathrm{B}_{\mathrm{c}}=\mathrm{B}_{\mathrm{a}}\left(1+\frac{\mathrm{h}^2}{\mathrm{r}^2}\right)^{\frac{1}{2}}$$

$$\mathrm{B}_{\mathrm{c}}=\mathrm{B}_{\mathrm{a}}\left(1+\frac{\mathrm{h}^2}{\mathrm{r}^2}\right)^{\frac{3}{2}}$$

$$\mathrm{B}_{\mathrm{c}}=\mathrm{B}_{\mathrm{a}}\left(1+\frac{\mathrm{h}^2}{\mathrm{r}^2}\right)^{-\frac{3}{2}}$$

A spherical surface of radius of curvature '$$R$$' separates air from glass of refractive index 1.5. The centre of curvature is in the glass. A point object $$\mathrm{P}$$ placed in air forms a real image $$\mathrm{Q}$$ in the glass. The line $$P Q$$ cuts the surface at point '$$O$$' and $$\mathrm{PO}=\mathrm{OQ}=\mathrm{x}$$. Hence the distance '$$\mathrm{x}$$' is equal to

$$1.5 \mathrm{~R}$$

$$2 \mathrm{~R}$$

$$3\mathrm{~R}$$

$$5 \mathrm{~R}$$
