Question
A particle executes simple harmonic motion with a frequency v. The frequency with which the kinetic energy oscillates is:
- $\frac{\text{v}}{2}$
- v
- 2v
- zero
✓
Answer
- 2v
Explanation:
Because in one complete oscillation, the kinetic energy changes its value from zero to maximum, twice.

A large spherical mass $M$ is fixed at one position and two identical point masses $m$ are kept on a line passing through the centre of $M$ (see figure). The point masses are connected by a rigid massless rod of length $\ell$ and this assembly is free to move along the line connecting them. All three masses interact only through their mutual gravitational interaction. When the point mass nearer to $M$ is at a distance $r =3 \ell$ from $M$, the tension in the rod is zero for $m=k\left(\frac{M}{288}\right)$. The value of $k$ is
