Que 15 A particle is projected along a horizontal surface whose coefficient of friction varies as A r 2 where r is the distance from the origin in metres and A is a positive constant The initial distance of the particle is 1 m from the origin and its velocity is radially outwards The minimum initial velocity at this point so the particle never stops is O 2 gA O 2gA
