i show the thing. i hope this helps
To solve this problem we will apply the concept of magnification, which is given as the relationship between the focal length of the eyepieces and the focal length of the objective. This relationship can be expressed mathematically as,
![\mu = \frac{f_0}{f_e}](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%5Cfrac%7Bf_0%7D%7Bf_e%7D)
Here,
= Magnification
= Focal length eyepieces
= Focal length of the Objective
Rearranging to find the focal length of the objective
![f_0 = \mu f_e](https://tex.z-dn.net/?f=f_0%20%3D%20%5Cmu%20f_e)
Replacing with our values
![f_0 = 7.5* 3.7cm](https://tex.z-dn.net/?f=f_0%20%3D%207.5%2A%203.7cm)
![f_0 = 27.75cm](https://tex.z-dn.net/?f=f_0%20%3D%2027.75cm)
Therefore the focal length of th eobjective lenses is 27.75cm
