Answer:
10x
Explanation:
The total magnification can be calculated by multiplying the power of eyepiece to the power of objectives. So, if you are looking for the magnification power of the objectives use the equation: objectives= total magnification/power of eyepiece.
Objectives= 50x/5x
Objectives =10x
Therefore, the magnification power of objectives that has been use is 10x.
