Hope it helps You My Friend :)
See the below images for your answer :) :-
Here, as per the provided question we will have to find that, how far is the screen from the Object
⟼ Magnification of the image = -3
⟼ Object placed in the front of mirror = -20 cm
⟼ [ (So, now let's find) ] Distance from the image = ?
Hence, let us find the image from the distance = ? (assuming image from the distance = x)
⟼ Magnification = Image (v) / Obj. Distance (u)
[ Substituting the values as per the provided formula use for this question to find the solution]
⟼ m = – v / u
⟼ -3 = - v /– 20
⟼ - 3 = v / 20
⟼ v = -60
⟼ (-3 × -20) = 60cm
⟼ 60cm = [ 60 -20cm]
Here, sign of (-) and (-) will be cut and the sign will come as (+)
⟼ (60 -20)cm = 40cm
Therefore, 40cm far the screen is from the Object.
