i think while talking about the nature of path we will have to take into consideration both the direction of acc. (force) on the particle as well as the direction of velocity in which the particle is already moving(if any) since all the options are incomplete the answer should be (d)
what are ur views??

velocity determines the ac instantaneous direction of the body
acc never determines the direction
nature of path is determined by an eq which can be 2d or 3d a second degree or anything which contains only direction vectors or constant .
i don't know how can one say acc. as the answer
man your concepts are shaking

the ans is none of these....quite obviously bcoz if any other ans. is taken into consideration the remaining two automatically get included...hence this is a question only for very shrewd atudents....

its simple.speed can only give inst.magnitude which is njot sufficient.velociyt givesw both mag.&dir. but only at that particular inst. so we cant say what happens next & hence cannot determine the immediatly next what happens so we are nuts about the immediate next pictue.accelaration tells us whre does ext.forces wanrs to drive the body but doesent take into accout its present state(its velocity) so we are nuts again.a b c are wrong the answer is both b& c if the body is macro. hence the answer is d.
