Answer:
0.6125 meters
Explanation:
We know that,
the height of the object (h) = 0.4 m,
the distance between the object and the mirror (u) = -0.7 m; and
the height of image (h') = 0.35 m.
For a concave spherical mirror, we know the formula of magnification:
magnification = [tex]\frac{h}{h'}[/tex] = [tex]-\frac{v}{u}[/tex]
[tex]\frac{0.35}{0.4} =\frac{-v}{-0.7}[/tex]
By cross multiplication:
[tex]v=\frac{0.35*0.7}{0.4}[/tex]
[tex]v= 0.6125[/tex]
Therefore, the image is located 0.6125 meters away from the mirror.
