Answer:
d) -4.0
Explanation:
The magnification of a lens is given by
[tex]M=-\frac{q}{p}[/tex]
where
M is the magnification
q is the distance of the image from the lens
p is the distance of the object from the lens
In this problem, we have
p = 50 cm is the distance of the object from the lens
q = 250 cm - 50 cm is the distance of the image from the lens (because the image is 250 cm from the obejct
Also, q is positive since the image is real
So, the magnification is
[tex]M=-\frac{200 cm}{50 cm}=-4.0[/tex]
