Question

an object is placed 35cm in front of a convex mirror of focal length 25cm. find the location and magnification of the object

Answer 1

Sorry I can't do it. It is so hard.

Answer 2

u= -35cm
F=25cm
1/f = 1/u + 1/v
1/25 = 1/ -35 +1/v
1/25+1/35=1/v
7/175+5/175 =1/v
12/175=1/v
V=175/12
V=14.6
It is 14.6cm behind the mirror
And without height of image or object we couldn't find magnification
