Question

The $x$-$t$ plot shown in the figure below describes the motion of the particle along $x$-axis, between two positions A and B. The particle passes through two intermediate points $P_1$ and $P_2$ as shown in the figure

• A. The instantaneous velocity is positive at $P_1$ and negative at $P_2$
• B. The instantaneous velocity is negative at both $P_1$ and $P_2$
• C. The instantaneous velocity is negative at $P_1$ and positive at $P_2$
• D. The instantaneous velocity is positive at both $P_1$ and $P_2$
• E. The instantaneous velocity is always positive

Hint:

Slope of $x$-$t$ graph gives velocity: upward slope $\Rightarrow$ positive, downward slope $\Rightarrow$ negative.

Answer 1

The Correct Option is A
