  1. Using parallel axis theorem ,
    I =Icm(about the centre of mass) + M(mass of the sphere)h2. where h is the required distance of the axis from centre of sphere
    MK2 = 2/5 MR2. + Mh2
    K2= 2R2/5 + h2
    R2 = 2R2/5. + h2. (given that. K=R. )
    3R2/5 = h2
    Which gives h=√3/5R2
    h=√0.6. R. (Answer)
