The velocity field for a plane vortex sink is given by \(\vec{V}=(-q / 2 \pi r) \hat{e}_{r}+(K / 2 \pi r) \hat{e}_{\theta}\), where \(q=2 \mathrm{~m}^{3} / \mathrm{s} / \mathrm{m}\) and \(K=1\) \(\mathrm{m}^{3} / \mathrm{s} / \mathrm{m}\). The fluid density is \(1000 \mathrm{~kg} / \mathrm{m}^{3}\). Find the acceleration at \((1,0),(1, \pi / 2)\), and \((2,0)\). Evaluate \(abla p\) under the same conditions.
