Question

What is the radius of curvature of the spherical mirror in the figure given if pa =10cm

Answer 1

Answer:Here (u) distance of object from mirror= -10

Focal length= -(1/2 of radius of curvature)

= -(1/2* 12) =-6

So by mirror formula we get,

1/F=1/V+1/U

-1/6=1/V-1/10

1/V=1/10–1/6

1/V=3/30 -5/30

1/V= -2/30

V= -15

DISTANCE OF IMAGE FROM MIRROR IS 15 cm left side of mirror

Explanation:

Answer 2

Explanation:

Here u= -10 cm

focal length = - (1/2* radius of curvature

-(1/2*12 = -6cm

using mirror formula

1/f = 1/v + 1/u

= -1/6 = -1/10 +1/v

1/v = 1/10 -1/6

1/v = 3-5/30

1/v = -2/30

v = -30/2

v =-15
