Answer:
The Mirror's radius of curvature is 18.45 m
Step-by-step explanation:
Radius of curvature (R) = 2 x Focal length (F)
Focal length = R / 2
Object distance (u) = 17 m
magnification = image distance (v) / Object distance (u)
0.35 = v / u
v = 0.35 u
Mirror formula
1 / F = 1 / u + 1 / v
1 /F = 1 /17 + 1 / -0.35u
1/F = 1/17 + 1 / -5.98
1/F = 1 /17 - 1 /5.98
1 / F = - 0.1084
F = - 9.225 m
Focal length is negative because the image formed is virtual.
Recall that: Radius of curvature (R) = 2 x Focal length (F)
= 2 x 9.225
Radius of curvature (R) = 18.45 m
