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
