1.	A convex length 15cm forms image 10 cm from the lens how far the object place from the lens draw diagram
Answer» Focal length (f ) = -15 cm Distance of IMAGE (v) = -10 cm 1v–1u=1f 1/u = -(1/10) – (1/- 15) 1/u =1/15 – 1/10 1/u = -0.033 u = -30 cm so the OBJECT is placed 30 cm away from the concave lens. RAY diagram
