dw:1316022392752:dw can you tell me how we get v  =\[v \cos \theta\] and v perpendicular = \[v \sin \theta\]

I think Parallel, Vertical all are taken with respect to xaxis so \(v_{parallel}\) is \(v\cos\theta\)

the angle θ is b/w your vsinθ and v

hmm do you know about sin ratios hmm okay Let me try again \[sin\theta = \frac{Perpendicular }{Hyp}\] so now try to apply this in the triangle the upper triangle

ok so vcosθ is Magnetic field and it is given in my notes that thus charge q will hav two motions linear and circular and hence resultant path is helix its axis along direction B dw:1316023925945:dw

how is it helix ? and how does it have linear and circular motions ?

hmm I think that is where electric field comes to effect

magnetic field makes it to move in circular motion but electric field makes it to move froward

Ishaan94 Group TitleBest ResponseYou've already chosen the best response.2
so hence helix is formed

Resolve the velocity into two components: one component parallel to the magnetic field; the other component perpendicular to it. The (assumed charged) particle will maintain the velocity that is parallel to the magnetic field, but will simultaneously move in circles in the plane perpendicular to the magnetic field. The combined effect is that it will "spiral" in a helix "following" the magnetic field.
