  • question_answer .A wheel is rolling on a plane road. The linear velocity of centre of mass is v. Then velocities of the points A and B on circumference of wheel relative to road will be

    A)  \[{{v}_{A}}=v,\,{{v}_{B}}=0\]          

    B)  \[{{v}_{A}}=\,{{v}_{B}}=0\]

    C)  \[{{v}_{A}}=0,\,{{v}_{B}}=v\]                

    D)  \[{{v}_{A}}=0,\,{{v}_{B}}=2v\]

    Correct Answer: D

    Solution :

     PointAisatrestw.r.t. motion, hence, vat \[A=0\] At point B there are two horizontal velocities. Hence, \[{{v}_{B}}=2v.\]
