The trailing vortex is formed at each wing-tip as there is a circulatory motion established by the____ Correct Answer Leaking flow at the wing- tips

The flow has a tendency to ‘leak’ around the wing-tips. This flow makes a circulatory motion that trails downstream of the finite weak, giving rise to trailing vortices. This flow is possible because of viscosity but it doesn’t happen because of viscosity.
