1.	A sphere is rolling without slipping on a fixed horizontal plane surface. In the figure, A is the point of contact, B is the centre of the sphere and C is its topmost point. Then A. (`i`),(`ii`)B. (`ii`),(`iii`)C. (`i`),(`iv`)D. (`ii`), (`iv`)
Answer» As in problem `133`, `vecv_(C)=2vhati` , `vecv_(B)=vecvhati`, `vecv_(A)=0` (`i`) `vecv_(C)-vecv_(A)=2(vecv_(B)-vecv_(C))=2(vhati-2vhati)=-2vhati`, incorrect (`ii`) `vecv_(C)-vecv_(B)=2vhati-vhati=vhati` , `vecv_(B)-vecv_(A)=vhati-0=vhati`, correct (`iii`) `\|vecv_(C)-vecv_(A)=2v`, `2\|vecv_(B)-vecv_(C)\|=2v`, correct (`iv`) `\|vecv_(C)-vecv_(A)\|=2v`, `4\|vecv_(B)\|=4v`, incorrect
