00:01 This question we are given a convex meter so here if you are given here convex meter so this convex meter used for the rear view use for the rear view and of automobile has a radius of curvature of automobile have a radius of the radius of curvature is equal we can write capital r equal to 3 meter if bus is located 5 meter here bus is located d which is equal to 5 meter from the mirror 5 meter from the mirror find the position and the nature and the size of image here we want to find here position position nature and the size of image this value we want to find here so let's solve this question and find out the answer so here we can write in this question we can write here we can write the object distance which is equal to you which is equal we can write minus 5 meter and the radius hook curvature are which is equal 3 meter and the convex meter focal lens we are given here f which is equal to plus 3 by 2 meter now using the meter formula so we can write 1 divided by f which is equal we can make 1 divided by v plus 1 divided by u now we just substitute value into this formula so here we can write 1 divided by v plus we can write 1 divided by minus 5 which is equal we can write 2 divided by now we just simplify and we can write 2 divide by 3 can write here answer is so we which is equal to answer here is 15 divided by 13 which is almost equal to we can write 1 .1538 meter let's talk about nature so image is virtual so here image here is the virtual image and behind the mirror so image is created behind the mirror so image is created behind the mirror so image is created behind the mirror now let's talk about here now i'm into magnification so we can write magnification m which is equal to h i divided by h0 which is equal we can write minus v divided by u now here we can write the h1 which is equal to minus so we view here value here so value of v we can write is minus 15 here we can write 15 divided by 13 divided by u value so value of u is minus 1 .5 and multiplied by h0 now we just simplify and we can write here answer is 10 divided by 13 multiple by h0 our correct answer of this question so which means we can write the magnification here m which is equal to magnification is 10 divided by 13 which is equal we can write is positive magnification is positive and also we can say and we can write less than 1 here we can write less than 1 so this is the correct answer and the convex manner will be created erect erect image virtual or we can say demeanish image here we can write image create is diminished.

03:20 So here this is our correct answer of this question...

Question

a convex mirror used for rear view of an automobile has a radius of curvature of 3m if a bus is located at 5m from the mirror . find the position , nature and size of the image
