Q. There are two blocks $A$ and $B$ in contact with vertical and horizontal smooth surfaces respectively, as shown in the figure. Acceleration of $A$ and $B$ are $a_A$ and $a_B$ respectively along their constrained direction of motions. Relation between $a_A$ and $a_B$ is (Assume $\left.\sin 23^{\circ}=2 / 5\right)$Physics Question Image

Laws of Motion

Solution:

Perpendicular to surface, their acceleration components must be equal.
$a_A \cos \theta=a_B \sin \theta$
$\sqrt{21} a_A=2 a_B$
