Hi everyone, we have a question in which this is given that we have a convex mirror for a rear view of a automobile which has a radius of curvature of 3 meter.
00:11
That means in the question this is given.
00:15
We have a convex mirror.
00:17
That means convex mirror.
00:20
Now for a convex mirror, radius of curvature should be positive because it is on the right side of the mirror.
00:26
So we can say radius of curvature which is given in the question.
00:35
Now since it is given as 3 meter, so we can take it as plus 3 meter.
00:40
So from the radius of curvature first thing that we can find the focal length.
00:43
So, focal length of the mirror which is f is equals to r by two, radius of curvature divided by 2, which is equal to 3 by 2 and which is nothing, it is equals to plus of 1 .5 meter.
00:59
Now, another thing this is also given in the question, a bus is which is located from 5 meter from the mirror, that means there is a bus which is located in front of the mirror at a distance of 5 meter.
01:13
So, we can say that object is placed, object distance from the mirror is also given in the equation which is at a 5 meter...
