• # question_answer 36) .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)  ${{v}_{A}}=0,\,{{v}_{B}}=2v$

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