Question 279 of 295

Given below are two statements : one is labeled as Assertion $A$ and the other is labeled as Reason $R$.
Assertion $A$: For a simple microscope, the angular size of the object equals the angular size of the image.
Reason $R$: Magnification is achieved as the small object can be kept much closer to the eye than $25cm$ and hence it subtends a large angle. In the light of the above statements, choose the most appropriate answer from the options given below:

A$A$ is false but $R$ is trueBBoth $A$ and $R$ are true but $R$ is NOT the correct explanation of $A$C$A$ is true but $R$ is falseDBoth $A$ and $R$ are true and $R$ is the correct explanation of $A$

Show answer and solution▾

Answer: (D) Both $A$ and $R$ are true and $R$ is the correct explanation of $A$

${\theta }^{'}=\dfrac{h}{{u}_{0}};{\theta }^{'}$ is same for both object and image
$m=\dfrac{{\theta }^{'}}{\theta }=\dfrac{D}{{\mu }_{0}}$
${u}_{0}\lt D$
Hence $m\gt 1$
