WebThe origin location (0,0) is called a singular point of the source ﬂow. As we approach this point, the magnitude of the radial velocity tends to inﬁnity as Vr ∼ 1 r Hence the ﬂow at the singular point is not physical, although this does not prevent us from using the source to represent actual ﬂows. We will simply need to ensure that ... Web(a) Determine the electric field strength at a point 1.00 cm to the left of the middle charge shown in the figure below.

In fluid dynamics, stagnation point flow represents the flow of a fluid in the immediate neighborhood of a stagnation point (or a stagnation line) with which the stagnation point (or the line) is identified for a potential flow or inviscid flow. The flow specifically considers a class of stagnation points known as saddle points where the incoming streamlines gets deflected and directed outwards in a different direction; the streamline deflections are guided by separatrices. …
