22:25 1) Answer is √3R Because it is an equilateral triangle of side 2R and when we take half of it as right angle triangle and apply Pythagoras theorem taking hypotenuse as 2R and base as R then we get the perpendicular i.e. r perpendicular as √3R. 31:02 2) Angle is 90° Because there are two types of accelerations i.e. tangential and centripetal and in uniform circular motion tangential acceleration is zero only centripetal acceleration acts and we know that centripetal acceleration is always directed towards centre and here it is perpendicular to the velocity. Thus, angle between velocity and net acceleration is 90°.

Amazing Lecture sir❤
1. Perpendicular distance √3 R aayegi aur I ki value : 9mr²/2 aayegi 2. Velocity and acceleration mein angle 90° hogi uniform circular motion ki

D = √3R Ans: 9MR^2/2
31:06 in case of uniform circular motion there is not at, so anet = ac, which means the angle bw linear velocity and anet will be 90°

Thankyou sir for this awesome strategy revision ❤🎉
22:14 R perpendicular Is √3R
Hme kb moment of inertia com k lena hai kb perpendicular axis theorem k MOI lena hai multiple mass me totally confused
Really amazing lecture 🔥🔥🔥🔥🔥
Iss question me d=√3 R Hoga aur moment of inertia=9MR²/2
Thanks you sir❤❤❤❤

22:25 Sir the perpendicular distance of body 1 from axis of rotation will be √3 R which we can put in the place of D in the formula ( Icm + Md^2) and if we consider these body as ring the Inet = 9mr^2/2 31:12 in ucm the angle b/w anet and v is 90°
