PhysicsEasysingle choice

A point object $O$ is placed in front of a glass rod having a spherical end of the radius of curvature $30 cm$ . The image would be formed at

Options:

Answer:

Solution:

By using lens maker's formula,

$\frac{μ ₂}{v} - \frac{μ ₁}{u} = \frac{μ ₂ - μ ₁}{R}$

$⟹ \frac{1.5}{v} - \frac{1}{(- 15)} = \frac{1.5 - 1}{+ 30}$

$⟹ v = - 30 cm$
