A mosquito $O$ is sitting infront of a glass rod having spherical end of radius of curvature $40 cm$ . The image would be formed at

Options:

Answer:

Solution:

As, we know, $\frac{μ _{2}}{v} - \frac{μ _{1}}{u} = \frac{μ _{2} - μ _{1}}{R}$ $\Rightarrow \frac{1.5}{v} - \frac{1}{( - 20 )} = \frac{1.5 - 1}{+ 40} v = - 40 cm$ Negative sign shows that image is obtained on the same side of object i.e., towards left.
