A truck uses convex mirror of radius of curvature 2.0m as a rear view mirror. A Maruti Car is coming behind the truck at a distance of 10m. what will be the position and size of the image of the car when observed by the truck driver?
Answers
The image is placed at position 10/11 and the size of the image is 10/11 m
Explanation:
Given data:
Radius(R)=2 m
Focal length(f) = R/2= 1 m
Applying lens mirror formula
1/v+1/u=1/f
1/v - 1/10 = 1/1
1/v= 1+1/10 = 11/10
v = 10/11 m
Position of the image will be 10/11 m in the mirror
Magnification(M) = v/u = (10/11) / (-10) = -1/11
Size of image= M*u = -10 x (-1/11) = 10/11 m
Thus the image is placed at position 10/11 and the size of the image is 10/11 m.

QUESTION: a truck uses a convex mirror as view finder whose radius of curvature is 2 m. A Maruti car is coming behind the truck at a distance of 10 m what will be the position of the image of the car when observed by the driver of the truck through the convex mirror
ANSWER:
radius(R)=2m
focal length(f) = R/2= 1m
applying mirror formula
1/v+1/u=1/f
1/v - 1/10 = 1/1
1/v= 1+1/10 = 11/10
v = 10/11m
position of the image will be 10/11 m in the mirror
magnification(M) = v/u = (10/11) / (-10) = -1/11
:. Size of image= M*u = -10*(-1/11) =
