The radius of curvature of a convex mirror used as a rear view mirror in a moving car is 2.0 m. A truck is coming form behind it at a distancce of 3.5 m. Calculate (a) position, and (b)size, of the image relative to the size of the truck. What will be the nature of the image ?

Explanation

To solve the problem step by step, we will use the mirror formula and magnification formula for a convex mirror.

### Given Data:
- Radius of curvature (R) = 2.0 m
- Distance of the truck from the mirror (u) = -3.5 m (negative because the object is in front of the mirror)

### Step 1: Calculate the focal length (f)
The focal length (f) of a mirror is given by the formula:
...
