Explanation Object is placed behind the diverging (concave)lens at 25 cm. A converging (convex)lens whose focal length is 12 cm, is placed at 30 cm to the right from the diverging (concave)lens. Final image formed by two lens systems is at 17 cm to the right of converging (convex)lens and the image is real and inverted. Given: Object distance from concave lens = 25 cm Focal length of convex lens = 12 cm Distance between both lenses is = 30 cm Distance of final image from convex (converging)lens = 17 cm Formula used: Lens formula for focal length 1 / f = 1 / v − 1 / u Calculation: For converging lens v=17 cm, f=12 cm, u=? 1 / f = 1 / v − 1 / u 1 / u = 1 / v – 1 / f 1 / u = ( 1 / 17 ) – ( 1 / 12 ) = ( 12 − 17 ) / ( 12 × 17 ) = − 5 / 204 u = − 204 / 5 = − 40 ⋅ 8 cm ( - sign means behind the lens ) so now for diverging lens v = (40∙8-30)cm = 10∙8 cm behind the diverging lens...

Students have asked these similar questions

A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?

Can someone help me with this question. Thanks.
