Question:medium

Two blocks $A$ and $B$ are released from rest on two inclined planes of the same inclination. One inclined plane is smooth while the other is rough as shown in the figure. If block $B$ takes $50\%$ more time to reach the bottom than block $A$, find the coefficient of friction $(\mu)$. The inclination of the plane is $45^\circ$.

Let the lines $L_1 : \vec r = \hat i + 2\hat j + 3\hat k + \lambda(2\hat i + 3\hat j + 4\hat k)$, $\lambda \in \mathbb{R}$ and $L_2 : \vec r = (4\hat i + \hat j) + \mu(5\hat i + + 2\hat j + \hat k)$, $\mu \in \mathbb{R}$ intersect at the point $R$. Let $P$ and $Q$ be the points lying on lines $L_1$ and $L_2$, respectively, such that $|PR|=\sqrt{29}$ and $|PQ|=\sqrt{\frac{47}{3}}$. If the point $P$ lies in the first octant, then $27(QR)^2$ is equal to}
