1.	calculate the distance at which an object should be placed in front of a convex lens of focal length 10cm
Answer» Convex lens gives the REAL and double-sized image when the object is placed exactly between the FOCUS and radius of curvature.We have, f1 = v1 − u1 m= UV =2 or v=2u∴ f1 = 2u1 − −u1 = 2u1 + u1 = 2u3 or 101 =2u3 or u=15cmplzzz MARK me a brainlist
