Homework Statement
the trajectory γ: ℝ→ℝ3 of a charged particle moving in a uniform magnetic field satisfies the differential equation γ''= B x γ'(t) . where B = (B1, B2, B3) is a constant 3-vector describing the magnetic field, and × denotes the vector product.
(a) Show that the particle travels at constant speed.
(b) Show that the component of the particle’s velocity in the direction of the magnetic field B is also constant.
Homework Equations
The Attempt at a Solution
Apart from knowing γ'' should =0 I have no idea how to show that, I just need a bump in the right direction on how to start
Thanks for any help
