[@sameersayam4991]

Very helpful....appreciated 👏🏻but requested if the solution of numerical based mcqs are provided.....would be more helpful

[@hurairagull6477]

Yes please

[@alishbamalik5851]

In mcqs no 9 correct option is A... Only momentum will conserved because In circular motion with a constant angular velocity, the kinetic energy of the particle remains change because its linear velocity keeps on changes due to motion hence only momentum is conserved

[@DrGHaris]

It's not velocity in the kinetic energy Eqn it's speed given by the dot product of velocity although momentum keep on changing due to existence of centripetal force

[@HibaLatif-k5q]

No

[@Am-hn7jz]

I thought it was momentum too

[@anna.theblogger]

When speed is constant angular velocity will not be constant only it's magnitude will be constant not it's direction because it's direction is changing at each interval

[@drbasheerchk]

Q 13 : relation bw angular and linear acceleration is option B (a=ra) not ar mery khiyaal sey..

[@xyzTrend123]

No! a=axr =racos@ a=ra

[@khansaad6669]

in vector form its a=ar not a=ra

[@Am-hn7jz]

4:04, A and C both are the same optionsss whaat btw I think its (a=ar)😊

[@alishbamalik5851]

In mcq no 25 if particle is moving in UCM then there won't be a constant energy while momentum will be conserved

[@nomijutt2468]

Thanks very helpful me

[@faiziii519]

Sir aap ka koi practice book hai ?

[@MissBaloch-sx8pn]

Q. No. 7 ko explain Karen plz

[@FazalRehman-x4h]

Madam kpk se taluk rakta hu mein pardsak ta hu es ko

[@QuizzyMCQs]

Yes

[@NajeebAsghar-pm3zg]

Mcq no 7 explain krden

[@aimantariq9614]

Good efforts 🙃

[@alishbamalik5851]

In mcq no 22 the correct option is d (zero) because if there's constant speed there will be no acceleration

[@scogzz0220]

You have to put the formula for centripetal acceleration which is (v^2/r)

[@onlypubg9303]

In Mcqs 22 D option is correct

[@osamanadeem1466]

Yeah u r right

[@Valvetdusk]

No b is right

[@abubakarcheema1662]

This sllybus is for last year .....not for present year Pls mam uploded new vídeos with right answer

[@xyzTrend123]

1st mcqs B. mark correct opt carefully .

[@medico78621]

Very helpful madam❤️

[@muzamilahmed8323]

22. D is correct

[@fatimafirdos7518]

If a particle move in a circle with constant speed it has only centripetal acceleration so use. a = V2/r

[@muzamilahmed8323]

How if speed is constant there acceleration will be zero

[@maheenmalik9953]

7 main konsa formula use howa?

[@Valvetdusk]

​@@maheenmalik9953v²/r

[@koonjfatima9688]

22 Ka answer d hai because speed is constant

[@durredarakhshan9303]

answer of 5 is c

[@SalmanMalik-oj6su]

Both a and b

[@zameerali2090]

13 ka B hai

[@faiziii519]

20/25😢

[@koonjfatima9688]

13B

[@koonjfatima9688]

8 Ka answer B hain

[@marsalangull]

20

[@drbasheerchk]

6 should be A

[@onlypubg9303]

21/25

[@SalmanMalik-oj6su]

B

[@khadijatahir5576]
