1.	A particle is projected in such a way that it follows a curved path with constant acceleration `vec(a)`. For finite interval of motion. Which of the following option `(s)` may be correct `:` `vec(u)=` initial velocity `vec(a)=` acceleration of particle `vec(v)=` velocity at `tgt0`A. `\|vec(a)xxvec(u)\|cancel(=)0`B. `\|vec(a)xxvec(v)\|=0`C. `\|vec(u)xxvec(v)\|=0`D. `\|vec(u).vec(v)\|=0`
Answer» Correct Answer - A::D If `\|vec(a)xxvec(u)\|=0` particle its will not forllow curved path. Above described motion is a projectile motion with parabolic path.
