PLS solve this two aerodynamics questions clearly. show all work.

Questions One: Problem $(2\mathrm{.}3)$ Consider a velocity field where the x and y components of velocity are given by u $=$ cx$($x$2+$ y$2)$ and v $=$ cy$($x$2+$ y$2),$ where c is a constant. Obtain the equations of the streamlines. $2\mathrm{.}3$ Consider a velocity field where the $x$ and $y$ components of velocity are

given by $u=c\frac{x}{x^2+y^2}$ and $v=c\frac{y}{x^2+y^2},$ where $c$ is a constant.

Obtain the equations of the streamlines.

Question Two:For the velocity field described in problem $2\mathrm{.}3,$ calculate the circulation around a circular path of radius R$.$
