    Note for my future reference :
    DONT YOU DARE FORGET THE FORMULAE! exam ke time panic karogi derivation ni ho payega
    r com = Sigma mi ri/ Sigma mi ( can work for ∆ displacements as well)
    Here, for continuous distributions: Integration r dm/ integration dm
    You can differentiate too to get v com , a com
    V v imp point
    In integration x dm/ M here x is COM of dx !!! Don't forget it!!!!!! it's not distance of dm from reference!
    ok that's it!✨😁

    Sir it might be a silly doubt but at 12:55 aapne y = 2r/pie kyu liya
    Disc ke liye to 4r/3pie hota haina
    Ya fir aapne jo element assume kiya vo maybe ring ki tarah hai to aapne aisa kiya
    But sir hm disc me element ko ring ki tarah to maan bhi nhi skte
    Plzzzzzzz reply sir🙏🙏🙏🙏

      The object might be a disc but here we are taking elementary mass as a ring
      since disc is nothing but rings of increasing radius , so y ill be com of ring
