Question

the object 5cm in length is placed at a distance of 20cm in front of convex mirror of radius of curvature 30cm find the position of the image size and nature​

Answer 1

Answer: -15cm

Step by step explanation:

Given,

Object (o) = 5cm

U = 20 cm

F = R/2 = 30/12 = 15 cm

                       

We have to find, the position of the image size and nature​

                             

According to Mirror Formula,

=> 1/f=1/v+1/u

                   

=> 1/15=1/v+1/20

                                       

                   => 1/v=1/15 -1/20

We get, V = 60 cm

                         

=> m= -V/U=I/O

                   

=> I =( -V/U)× O

                 

= -60×5/20

                                            =   -15 CM

                                       

Therefore, -15 cm is the position of the image size and nature​
