✓
$(A \rightarrow r, B \rightarrow q, C \rightarrow s, D \rightarrow p)$
B
$(A \rightarrow q, B \rightarrow r, C \rightarrow s, D \rightarrow p)$
C
$(A \rightarrow r, B \rightarrow s, C \rightarrow q, D \rightarrow p)$
D
$(A \rightarrow r, B \rightarrow q, C \rightarrow p, D \rightarrow s)$

✓

Answer

Correct option: A.

$(A \rightarrow r, B \rightarrow q, C \rightarrow s, D \rightarrow p)$

a
(a)

We have to analyse slope of each curve i.e. $\frac{d x}{d t}$. For peak points $\frac{d x}{d t}$ will be zero as $x$ is maximum at peak points.

For graph $(A)$, there is a point $(B)$ for which displacement is zero. So, a matches with $(r)$.

In graph $(B)$, $x$ is positive $\diamond 0$ ) throughout and at point $B_1, V=\frac{d x}{d t}=0$

since, at point of curvature changes $a=0$, So $b$ matches with $(q)$

Two small, equal masses are attached by a light weight rod. This object orbits a planet ; the length of the rod is smaller than the radius of the orbit, but not negligible. The rod rotates about its axis in such a way that it remains vertical with respect to the planet. (Assume in each case perturbation maintains the rate of rotation, so that in the co-rotating frame the rod is still stationary but at an angle to the vertical.)
