1.	A plano-convex lens of curvature of 30 cm and refractive index 1.5 produces a real image of an object kept 90 cm from it. What is the magnification?A. 4B. 0.5C. 1.5D. 2
Answer» Correct Answer - D We have, `(1)/(v)-(1)/(-90)=(1)/(f)rArr (1.5-1)((1)/(30))=(1)/(60)` `therefore " " v=180 cm` `therefore " " \|m\|=\|(v)/(u)\|=(180)/(90)=2.0`
