Question

Question: A convex mirror used in a bus has radius of curvature 3.5 metre and if the driver of the bus locate a car at 10 metre behind the bus find the position nature and size of the image of the car​

Answer 1

Hey mate,..

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

Hope it will help you
