1.	A concave mirror produces three times magnified image on a screen. If the object is placed 20 cm in front of the mirror, how far is the screen from the object?
Answer» Answer: distance of SCREEN from mirror = image distance Explanation: MAGNIFICATION(m)= +3.0 or 3 object distance(u)= 20 cm image distance(v)= ? m= -v/u => 3 = -v/-20 => v = 20 x 3 => v= +60 cm plz mark me as the brainliest.

Answer»

Answer:

distance of SCREEN from mirror = image distance

Explanation:

MAGNIFICATION(m)= +3.0 or 3

object distance(u)= 20 cm

image distance(v)= ?

m= -v/u

=> 3 = -v/-20

=> v = 20 x 3

=> v= +60 cm

plz mark me as the brainliest.
