[monke]

Homework Statement

An object 2.00cm high is placed 12.0cm in front of a convex mirror with radius of curvature of 8.00cm.

Homework Equations

Where is the image formed? Draw a ray diagram

The Attempt at a Solution

do i use the equation m=-q/p? if so then (object distance)p= 12cm. how do i find q using the information given?

Thank you

actually i may have gotten it. if i find f using f=(1/2)R the pulg into the mirror equation
1/p+ 1/q = 1/f and solve i have the answer?
