Not 77.62
Thanks you so much

sir in side box information question no 4
please answer according to question
tell the power of lens not the position of object answer that what is power of lens in diopters

bro agr apka 12.5 numerical thk bhi ho to hm ye follow nhi kr skty kyu ki hamary examiners lakeer ky faqeer hoty wo skill nhi just ability to learn everything word by word yani ratta check krte

exercise multple question no 2 wrong correct answer 15 cm

It’s correct answer is 6.2cm.

Not 77.62

Thanks you so much

Review questions kahan hai ??

Yes its 77.62 because it is convex lens q and f should be negative.

Sir,numerical 2 ke (a) portion mai answer negative kyun nhi hai?

It should be negative as in calculation 55 was negative

Because distance can’t be negative.

its not convex lens its convex mirror here f will be positive and q will be negative

study topic of spherical mirrors carefully and you will know

Review questions are not available… Please upload.

In numerical 12.2 it is 10.5 not 105

No mistake, point is shifted to right. so it becomes 10/105

sir in side box information question no 4

please answer according to question

bro agr apka 12.5 numerical thk bhi ho to hm ye follow nhi kr skty kyu ki hamary examiners lakeer ky faqeer hoty wo skill nhi just ability to learn everything word by word yani ratta check krte

ya bro you are right 👍 hamare examiners no writing skills no learning skills

No answer of numerical no 5 is right on book it was wrong in this page

12.5 waley numerical ka ans galat hai us me focal length bhi negative aani hai kion k convex mirror ki focal length negative hoti hai

ok, we’ll check it.

We Need new book notes ( national book foundation ) Test Edition

Numerical no.5 is wrong as focal length and image is negative so the ans in book is correct.Please check it.

Ok, We’ll check it.

Numerical no is wrong plz check it😊

numerical 5 is righ guys

Numerical no.5 answer is not correct. Please check it.

ok, we’ll check it.

The numerical 12.6 is wrong as the answer of part (b) is 3.84. My teacher solved it on the board but I forgot to write it down.

ok, we’ll check it.

12.5 numerical is correct because it is a convex mirror not a concave mirror therefore focal length is +ve and the answer is 77.625
