Hi. In the given problem, there are two lenses. The first one is a convex lands, and the second one is a concave alliance, and the school dances are kept at a distance off one at a distance of 50 centimeter between them, the focal length off first plants. The convex lens has been given us 25 centimeters, and the Oakland off second Convex lens has been given us minus 40 centimeters. An object has been kept in front. Off this, convicts lands at a distance off 30 centimeters. So as for sign convention for the first plans, this is minus 30 centimeter. In the first part of the problem, we have to find the final position off the image formed by the combination by this lens combination. Hence, for the first plans, use England's equation, which is a relation. Among the object is stance, image, distance and for Colette. So it says, one by Cuban minus one by even visible to one by F one. Or we can say one by Cuban minus one by minus 30 is equal to one by 25. Or this is one by Cuban is equal to one by 25 minus one by Kirby Hell, This Elsie, um, comes out to be 150. This is six minus five or one by 150. So we can say that image formed by this first plans. Really? Each one by this first plans should have seen at a distance. So 150 centimeters towards the right. So these are the incident lease he is coming from The object thes raise should have informed and image off this object a distance off 150 centimeter. But before that, this concave Elin's intercept the race So this concave lens will divert stories further away from that combination. Hence, for the second lands, this image will serve as the virtual object. So the distance for this virtual object comes out to be be to which is given by 1 50 minus 50. Or this is plus 100 centimeters for the second lands. And we know the focal length after his minus 40 centimeters. So using violence situation again one bite, que tu minus one by P two is equal to one by f two, or you can say one bike uto. This is missing minus one by 100 off. Positive sign equals toe one by minus 14. So this one like you too becomes one by 100 minus one by 14. Who's Elsie? Um, Comes out Toby 200. So this is Tu minus. Hi. What we can say this is minus tree by 200. So finally this Kyoto, the distance off image from by this concave lens comes out B minus 200 by cream or this is minus six 36.67 centimeter or roughly, we can say minus 67 centimeters from the second lens. So this is the answer for the first part of the problem and negative sign on Lee for sign Convention for the rial distance off, this final image is 60 70 67 centimeter from the second lands the works Right now, In the second part of the problem, we have to find the orientation off this image. So, using the expression for the next leader magnification, chemicals toe anyone into empty, or this is Cuban by even multiplied by Q 25 p two. So putting all these known values here this is 150 for Cuban minus 30 For Stephen. This is minus 67. 4. You so And for Peter Business 100. So ultimately it comes out to be positive. Hence we can say the final images erect. And as the final images area can be informed, toe the right off the lands combination. In the last part of the problem, we can see this final in each is virtual as only virtual images are red. Thank you.
