1:11:52 Mei C2 ko aise Kiya: If the vernier scale is moved slightly towards left so that zero of vernier scale mathches with 28mm in mains scale, then the seventh division on vernier scale is 7.7mm far from the zero of vernier scale. The eight division(starting from 28mm line) on main scale is the one with which vernier's seventh division has overlapped before. The eight (measuring from 28mm line) division on main scale will be 8mm away from 28mm mark on main scale. So the seventh division of vernier calliper has to cover 8mm - 7.7mm = 0.3mm, in order te get matched with the eight division (measuring from 28mm line). So we have to add 0.3mm to 28mm. Answer = 28 + 0.3 = 28.3mm
1:14:46 I did C2 like this: From main scale 28mm mark to 36mm mark, the distance is 8mm. From vernier scale 0 mark to 7 mark, the distance is 7.7mm. So the distance between 0 mark on vernier scale and 28mm mark on main scale is given by 8mm - 7.7mm = 0.3mm So the total distance between zero of main scale and zero of vernier scale is 28mm + 0.3mm = 28.3mm
thnkuu so much sir, bht hi ache trike se btaye optical instruments, otherwise phle ye sbse zada critical or confusing lgta tha like kch pta ni chlta tha, but you teaches in very nice and easy way❤️❤️ dhanyawad sir❤️❤️🙏🏻 aapne crystal clear krdia concept💓
Pls explain sir ne 1:35:53 pe zero error kaise li sir ne 0.01 se multiply kyu nhi kiya and -0.5 pahale kaise likha vernier pe toh -1+0.1 something lete the
Agar 75 na bane aur Drop le liya........ To CBSE Improvement de dena agle saal ya isi saal jis hisaab se marks kam aaye to araam se nayi marksheet with 75+ marks banke aayegi aur usse IITs NITs sb mil jayenge
Is there anybody who is currently scoring 70+ in chemistry? if yes pls give me a brief on all three subjects of chem about what u studied and how u made it to 70+, chem is my only weak subject, your input will help me a lot🙏🙏
Kinematics aur WPE karle kaafi jagah use hoota h .... bakki thoda gravitation will help in Electrostatics ... that's it don't stress out on 11th .... focus on 12th more .... else you will regret

1:11:52 Mei C2 ko aise Kiya:
If the vernier scale is moved slightly towards left so that zero of vernier scale mathches with 28mm in mains scale, then the seventh division on vernier scale is 7.7mm far from the zero of vernier scale. The eight division(starting from 28mm line) on main scale is the one with which vernier's seventh division has overlapped before. The eight (measuring from 28mm line) division on main scale will be 8mm away from 28mm mark on main scale. So the seventh division of vernier calliper has to cover
8mm - 7.7mm = 0.3mm, in order te get matched with the eight division (measuring from 28mm line). So we have to add 0.3mm to 28mm.
Answer = 28 + 0.3 = 28.3mm
1:14:46 I did C2 like this:
From main scale 28mm mark to 36mm mark, the distance is 8mm. From vernier scale 0 mark to 7 mark, the distance is 7.7mm. So the distance between 0 mark on vernier scale and 28mm mark on main scale is given by
8mm - 7.7mm = 0.3mm
So the total distance between zero of main scale and zero of vernier scale is
28mm + 0.3mm = 28.3mm

sir 12th ke abhi exam diye hai agar 75% na bane fir bhi 1 sal drop leke jee main ka exam deker private university se b tech kar le
Agar 75 na bane aur Drop le liya........ To CBSE Improvement de dena agle saal ya isi saal jis hisaab se marks kam aaye to araam se nayi marksheet with 75+ marks banke aayegi aur usse IITs NITs sb mil jayenge
prepare for jee and go to top government colleges like DTU , NSUT or MAIT ,MSIT etc. they require 60% in 12th boards
