Match the corresponding entries of column 1 with column 2. [where m is the magnification produced by the mirror

Answer

C

Explanation

Magnification in the mirror, `m=-(v)/(u) m=-2impliesv=2u`
As v and u have same signs so the mirror is concave and image formed is real.
`=((1)/(5)+1)^(2)/(((1)/(5)-1)^(2))=(((6)/(5))^(2))/((-(4)/(5))^(2))=(36)/(16)=(9)/(4)` Concave mirror and real image. `m=+2impliesv=-2u`
As v and u have different signs but magnification is `2` so the mirror is concave and image formed is virtual.
`m=+(1)/(2)impliesv=-(u)/(2)`
As v and u have different signs with magnification `((1)/(2))` so the mirror is convex and image formed is virtual.
