Question
A particle is in linear simple harmonic motion between two points $A$ and $B, 10\ cm$ apart. Take the direction from $A$ to $B$ as positive direction and give the signs of velocity and acceleration on the particle when it is :
  1. At the end $B$.
  2. At $3\ cm$ away from $A$ going towards $B$.
✓

Answer


  1. At the end $B$ velocity is zero. Here acceleration and force are negative as they are directed along $BR$ i.e., along negative direction.
  2. At $3\ cm$ away from $A$ going towards $B$, the particle is at $R$, with a tendency to move along $RP$ which is positive direction, here velocity, acceleration are all positive.

The principle of ‘parallax’ in section $2.3.1$ is used in the determination of distances of very distant stars. The baseline AB is the line joining the Earth’s two locations six months apart in its orbit around the Sun. That is, the baseline is about the diameter of the Earth’s orbit $\approx 3 \times 10^{11} \mathrm{~m}$. However, even the nearest stars are so distant that with such a long baseline, they show parallax only of the order of $1”$ (second) of arc or so. A parsec is a convenient unit of length on the astronomical scale. It is the distance of an object that will show a parallax of $1”$ (second of arc) from opposite ends of a baseline equal to the distance from the Earth to the Sun. How much is a parsec in terms of metres?
