A rear view mirror has a radius of curvature 4m. An image of a bus is formed 1.5 m behind the mirror. Find the actual distance of the vehicle from the mirror and compare the size of the bus with the image seen in the mirror

here , f = 4m
v = 1.5m
u =?
by mirror formula
1/f=1/v+1/u
1/4=1/1.5+1/u
1.5-4/6=1/u
2.5/6=1/u
5/12=1/u
12/5=u
u=2.4 m
the actual distance of the vehicle is 2.4 m
the SIZE of image of bus is smaller than bus
I hope it's helpful

butterfly36:
radius of curvature is 4m not focal length
focal length must be 2m as r=2f
sorry
