Question

Match the corresponding entries of column 1 with column 2.
[Where m is the magnification produced by themirror]

Options

A.

A → b and c; B → b and c; C → b and d; D →a and d

B.

A → a and c; B → a and d; d → a and b; D → c and d

C.

A → a and d; B → b and c; C → b and d; D → b and c

D.

A →c and d; B → b and d; C → b and c; D →a and d

Solution

m = -Vu=ff×u
m = -2 then "V" and "u" same given
-2 = ff×u - 2f + 2u = f
= 3f = - 2u
+3f2=4
For mirror so 4 negative
∴ V has to be negative
