PhysicsEasysingle choice

A particle is moving in a circle of radius $1 cm$ and with a constant speed of $8 cm s^{- 1}$ . Centre of the circle lies on principal axis of a converging lens of focal length $50 cm$ and at a distance of $75 cm$ from the lens. Plane of the circle is perpendicular to principal axis,. The correct statement is

Options:

Answer:

Solution:

$m = \frac{f}{f + u} = - 2$

$\Rightarrow$ radius of image = $2 cm$

$∵ ω$ is same

$\Rightarrow \frac{8}{1} = \frac{v}{2} \Rightarrow v = 16 c m s^{- 1}$ .
