1.	A convex lens forms a real and inverted image of a needle at a distance of 50 cm from it Where is the needle placed in front of the convex lensif the image is equal to the size of the object? Also find the power of thelens.
Answer» py Soul ❤Your Answer :The position of image should be at 2F, since the image is real and same size.It is given that the image of the NEEDLE is formed at a distance of 50 cm from the convex lens. THEREFORE, the needle is placed in front of the lens at a distance of 50 cm.Focal length :Object distance (u) = - 50 cmImage distance, (v) = 50 cmFocal length = fAccording to the lens formula,1/v - 1/u = 1/f1/f = 1/50 - 1/(-50)1/f = 1/50 + 1/501/f = 1/25f = 25 cm = 0.25 MPOWER of lens :p = 1 / f ( in meter)p = 1/0.25 = +4 DHope this will helps you ☺Note : Thanks to my answers n ho ske to follow VI kar LO ❤
