Aconvex lens of focal length 35 cm produces a magnified image 2.5 times the size of the object. what is the object distance if the image (formed) is real?

Image distance is -52.5 cm

Image is virtual and forms on the same side of the lens and upright image is formed.

Explanation:

u = Object distance

v = Image distance

f = Focal length = 35

m = Magnification = 2.5

Lens equation

Image distance is -52.5 cm

Image is virtual and forms on the same side of the lens and upright image is formed.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

the body's situation won't change the forces are equal opposit and on the same body
