Question

Displacement x of a particle moving in one dimension is related to time t by the equation $t=\sqrt{x}+2$. The displacement of the particle when its velocity is zero, is (Here x is in metre and t is in second)

• A. 4
• B. 2
• C. 1
• D. 0

Answer 1

The correct option is D 0

since displacement is integration of velocity and velocity is differentiation of displacement .we are given that velocity is zero so we will form an equation and differentiate it w.r.t time and determine the respected value of time for which velocity is zero and on solving we get option D is answer.
