$\lambda \propto V \propto \sqrt{\frac{T}{\mu}}$
New $\frac{\lambda^{\prime}}{\lambda}-\frac{\sqrt{2 T}}{\sqrt{T}} \Rightarrow \lambda^{\prime}=\sqrt{2} \lambda$
$\frac{\lambda^{\prime}}{2}=\sqrt{2} \cdot \frac{\lambda}{2}=\sqrt{2} \mathrm{x}$ Ans.

Give the answer question $1,2$ and $3.$
$\theta = 2{t^3} + 0.5,$
where $\theta $ is in radians and $t$ is in second. Then the angular velocity of the particle after two second will be ....... $rad/sec$
