What would be the magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x?
a.) 40x
b.) 50x
c.) 400x
d.) 500x

The magnification of a specimen viewed with a compound light microscope that has an objective power of 40x and an ocular lens power of 10x is 400x. The correct answer between all the choices given is the third choice or letter C. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the bal will not change its velocity.
