If a microscope has a 10x ocular and the total magnification at a particular time is 950x, the objective lens is use at that time is x.

The correct answer will be- 95X.

Explanation:

Magnification of a microscope is the amount of the visual enlargement of the observed object.

The magnification of a microscope can be increased by changing the lens closer to the object called an objective lens while the ocular lens close to the eyes remain fixed.  The magnification is a result of the multiplication of the power of the ocular lens to the objective lens like in the given case:

Magnification= power of ocular lens X power of the objective lens.

950 X = 10X x P(o)

P (o)= 95X

Thus,  95X is the correct answer.
