Question

Convex mirror used as a rear view mirror of focal length 3m and the bus and 5 M find the image distance

Answer 1

convex

F=+3

U=-5

1/F=1/V+1/U

1/3=1/V-1/5

1/V=1/3+1/5

V=15/8

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
