Physics · MOTION IN A STRAIGHT LINE
हिन्दीA particle moves in simple harmonic motion along the x-axis. At a certain instant, its position coordinate is negative (\( x < 0 \)) and it is moving towards the origin. What are the correct signs of its position \( x \), velocity \( v \), and acceleration \( a \) at this instant?
Correct answer · Option 4
\( x < 0, v > 0, a > 0 \)
Explanation
Position \( x < 0 \) is given. Since it moves towards origin (towards positive x), velocity \( v > 0 \). For SHM, \( a = -\omega^2 x \); since \( x < 0 \), acceleration \( a > 0 \).
