When magnified 1,000 times by an electron microscope, the image of a certain circular piece of tissue has a diameter of 0.2 centimeter. The actual diameter of the tissue, in centimeters, is Choose the correct choice from the following
A) 0.005
B) 0.002
C) 0.001
D) 0.0005
E) 0.0002
It is very easy if x is the diameter, then the magnified length is 1000x.   ince 1000x=0.2 then x=0.2/1000=0.0002.   The answer is 0.0002
