Question

The focal length of spherical mirror, if the object
distance u = (50.1+0.5)cm and image distance
V = (20.10.2) cm, will be
(1) (12.2+0.2) cm
(2) (14.3+0.1) cm
(3) (10.2 +0.1) cm
(4) (15.1+0.3) cm​

Answer 1

Answer:

$\frac{1}{f} = \frac{1}{u} + \frac{1}{v} \\ \frac{1}{f} = \frac{1}{50.6} + \frac{1}{20.3} \\ \frac{1}{f} = \frac{20.3 + 50.6}{1027.18} \\ f = \frac{1027.18}{70.9} \\ f = 14.48 \\ f =14.3 + 0.1 \\ anssssssssssssssssssssssss$
