2:40:55 Answer shd be option D.....we can solve it by 2 ways...First, apply the simple rules for concave mirror..The object placed beyond 2F makes the image between F and 2F and is real image...So that makes the answer -45cm and we get the option. Also the image formed is diminished. Another method will be the mathematical method. I bet everyone watching this lecture got the correct answer. Correct me if i am wrong

In NEET 2020 , Questions asked from mechanics - 12 ( 6-7 chapters including the huge time consuming topics like- System of particles and laws of motion ) Whereas, In Modern Physics there are only 4-5 chapters and questions asked in NEET 2020 were 8. So,. Q/chap density is high enough in modern physics than mechanics.

[@ishitamishra1747]

I respect all the pw team....🙏🙏 But I need only Alakh sir for my physics....He is only one.... because of him I scored now 110+...where I was started form 29.... I want Alakh Sir.... Please sir come back to us...

Pls it's a request to alakh sir . That don't give wave optics lecture to any other teacher it's a big n important chatpter . He himself should take that lec. I had studied Ray optics earlier as well watching this for rivison n got confused . N topics are also not matching from the yakeen lectures. Pls sir aap he kariye ga waves optics Baki dusre chpter koi or teacher se kra lijiyega. Humble request.
