Question

A particle situated at x = 0, moves at t = 0 in positive X-direction with velocity u which changes according to relation u = \(\alpha\sqrt{x}\). Displacement of the particle changes with time in this way:

(a) t²

(b) t

(c) t^1/2

(d) t³

Answer 1

Correct option is : (a) t²

Thus, x changes according to t². Hence option (a) is correct.
