WebIf θ = 0∘, the charge undergoes helical motion with its pitch increasing with time, along the y-axis. D If θ = 0∘, the charge undergoes linear but accelerated motion along the y-axis. Solution: (a) and (b) Magnetic field will rotate the particle in a circular path (in x-z plane or perpendicular to B). In aviation, geometric pitch is the distance an element of an airplane propeller would advance in one revolution if it were moving along a helix having an angle equal to that between the chord of the element and a plane perpendicular to the propeller axis; see also: pitch angle (aviation). Meer weergeven A helix is a shape like a corkscrew or spiral staircase. It is a type of smooth space curve with tangent lines at a constant angle to a fixed axis.
