3.33cm
5.00cm
6.67cm
8.50cm
Correct answer is A
\(\mu\) = R.9 = 1.5 = 10
A.P A.d, Ad = 6.66
Displacement = R.d - A.d = 10 - 6.66
= 3.33

The magnification of an object 2cm tall when placed 10cm in front of a plane mirror is
6.0
1.0
0.7
0.6
Correct answer is B
M = v = \(\frac{2}{2}\) = 1
25m
50m
100m
150m
Correct answer is D
==> \(\frac{v}{u}\) = \(\frac{hi}{ho}\)
==> \(\frac{5}{300}\) = \(\frac{2.5}{ho}\)
= 150m
