Answer 2

Answer:

position of image=10cm from the pole

nature of image= virtual and erect

size of image=20/3cm

Explanation:

position of image is found by the classic mirror formula(1/v+1/u=1/f) with proper sign conentions here u and f are negative since it is a concave mirror

to find size of image we use m=hi/ho=-v/u

hereu is negative so equation becomes hi/ho=v/u
