In my school we solved Q3 like: *Given: length of the object (h¹)= 10 cm ; focal length (f)= -10 cm ; distance of object (u)= -20 cm* *To Find: length of the image (h²)= ?* *Solution* : According to the mirror formula, 1/v + 1/u = 1/f 1/v = 1/f - 1/u = 1/-10 - 1/-20 = -(1/20) .•. v = -20 cm M= h²/h¹ = -(v/u) h²/10 = -(-20/-20) h²= -(20/20) × 10 [minus cut] h²= -10 cm .•. The length of the image is 10 cm (idk how the teacher managed to remove the minus sign, if you know how, let me know too 👇)

[@hafijurrahman6992]

Thanks for the solution actually

[@akashtemkar1320]

Actually thank you

[@MeenaGupta-nd5ee]

Length of image while writing the final answer is always positive. Height of any image or object cannot be negative

Sir all chapter ke exersice layiye please

[@mohammadjunaid4691]

Why values are taken in negative form????

[@bhagwatimop9648]

Chup rehna

[@febinadabre3450]

Because the object is always kept at the left and according to Cartesian sign conventions it should be negative textbook page no 125

[@jatinsrivastava4499]

Well its because of the concave mirror , inverted means upside down , the farther u are from the concave mirror , the smaller the object appears and the image tilts upside down. Inverted just denotes the question negative , therefore the focal length , the height , everything is gonna be denoted in negative :)
