The spherical side mirror on a car is convex and has a radius of curvature of 25 cm. another car is following, 20 m behind the mirror. if the height of the car is 1.6 m, how tall is its image? (a) 5.0 cm (b) 2.0 cm (c) 4.0 cm (d) 0.99 cm

(D) 0.99 cm

Explanation:

Given that the radius of curvature of the mirror is 25 cm.

And another car is following which is behind the mirror of 20 m.

Focal length is half of the radius of curvature and it is negative for convex lens.

Now the mirror formula.

So,

Now

Magnification is,

So,

So, Height of the image

Therefore, the image height is 0.99 cm.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential
