A Shop Security Mirror 5.0 M from Certain Items Displayed in the Shop Produces On-tenth Magnification. What is the Radius of Curvature of the Mirror? - Science

A shop security mirror 5.0 m from certain items displayed in the shop produces on-tenth magnification. 

What is the radius of curvature of the mirror?

Distance of the object (u) = -5 m
Magnification (m) = `1/10`
We have to find the position of the image (v), radius of curvature (R) and the focal length of the mirror (f).

Using the magnification formula, we get 
`v=0.5  m`
Now, using the mirrorformula, we get  
or, R = 1.1
Therefore, the radius of curvature of the mirror (R) is 1.1 m.
Concept: Convex Mirror
  Is there an error in this question or solution?
