Answer:
The magnifying power of this telescope is (-60).
Explanation:
Given that,
The focal length of the objective lens of an astronomical telescope,
The focal length of the eyepiece lens of an astronomical telescope,
To find,
The magnifying power of this telescope.
Solution,
The ratio of focal length of the objective lens to the focal length of the eyepiece lens is called magnifying of the lens. It is given by :
m = -60
So, the magnifying power of this telescope is 60. Therefore, this is the required solution.
From the law of the lever:
<span>mechanical advantage= input arm : output arm
input arm- a
output arm-b
</span>
<span>Input arm is equal 4,8m</span>
<span>mechanical advantage= input arm : output arm
