1.	The kinetic energy of a particle continuously icreses with timeA. the resultant force on the particle must be parallel to the velocity at all instants.B. the resultant force on the particle must be at an angle less than `90^(@)` with the velocity all the timeC. its height above the ground level must continuously decreasesD. the magnitude of its linear momentum is decreasing continuously
Answer» Correct Answer - B `dW_(F)=vec(F).vec(ds)=dk gt 0rArr \|vec(F)\|\|vec(ds)\|cos theta gt 0` `rArr 0 lt theta lt 90^(@)` `p=sqrt(2m(KE)), KE uarr ` so `p uarr`.
