Question

A convex mirror used in a bus has radius of curvature 3.5m. If the driver of the bus locates a car at 10m behind the bus find the position , nature and size of the car

Answer 1

R=3.5m
U=-10m
V=?

f=R/2=1.75m

1/f=1/v+1/u

1/v=1/f-1/u = 1/1.75 - 1/-10

1/v=1/2.12m

V= 2.12m

ANSWER:-----------------

R= 3.5

U= 10.0

f= R/2   =3.5/2

3.5°10/2°10

35/20

7/4

1.75

1/f= 1/v +1/u    1/v =  1/f- 1/u       1/v= 1/1.75-1/-10

= 1/7/4-1/-10   =4/7- 1/-10

= -40-7\ 70 = 47/70

v = 70\47

v = 1.5

m= -v\u

m = -1.5\[-10]

= 0.15 An
