Answer 2

Answer:

Radius of Curvature (R): 8 cm

Focal Length (f) = R/2 = 8/2 = 4 cm

Object distance (u) = -10 cm

Image Distance (v) = ?

We know that,

Mirror Formula:

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

= -1/4 = 1/v - 1/10

= -1/4 + 1/10 = 1/v

= 1/v =  

= 1/v = -3/20

v = -20/3 cm = cm

∴ Real Images are Inverted.
