The eye will be able to focus on the image if $x \geq D$. The correct lens equation is: (a) $\frac{1}{\mathrm{u}}=\frac{1}{\mathrm{f}}+\frac{1}{\mathrm{x}}$ (b) $\frac{1}{\mathrm{u}}=\frac{1}{\mathrm{f}}-\frac{1}{\mathrm{x}}$ (c) $\frac{1}{\mathrm{u}}=\frac{1}{\mathrm{x}}-\frac{1}{\mathrm{f}}$ (d) $\frac{1}{\mathrm{u}}=-\frac{1}{\mathrm{x}}-\frac{1}{\mathrm{f}}$
Two thin lenses of focal length $\mathrm{f}_{1}$ and $\mathrm{f}_{2}$ are coaxially placed in contact with each other then the power of combination is (A) $\left[\left(\mathrm{f}_{1}+\mathrm{f}_{2}\right) / 2\right]$ (B) $\sqrt{\left(f_{1} / f_{2}\right)}$ (C) $\left[\left(\mathrm{f}_{1} \mathrm{f}_{2}\right) /\left(\mathrm{f}_{1}+\mathrm{f}_{2}\right)\right]$ (D) $\left[\left(\mathrm{f}_{1}+\mathrm{f}_{2}\right) /\left(\mathrm{f}_{1} \mathrm{f}_{2}\right)\right]$
Two plano-convex lens each of focal length $f$ are placed as shown in figure. The ratio of their focal lengths is:(a) $1: 2: 3$ (b) $1: 1: 1$ (c) $1: 2: 1$ (d) $3: 2: 1$
