STANDARD Physics Simple Harmonic Motion MCQ Question
A particle is in linear simple harmonic motion between two points A and B, 10 cm apart (figure). Take the direction from A to B as the +ve direction. Which of the following statements is correct?
The sign of acceleration and force on the particle when it is at A is negative.
The sign of acceleration and force on the particle when it is at B is positive.
The sign of velocity, acceleration and force on the particle when it is 3 cm away from A going towards B are positive.
The sign of velocity, acceleration and force on the particle when it is 4 cm away from B going
Correct Answer
Detailed Explanation
For SHM, acceleration and force are always directed towards the mean position. It is given that the direction A to B is positive. At 3 cm from A towards B, all signs are positive.
