Problem

The electric and magnetic fields in a region of space are

\mathbf{E}=E_0\hat{\mathbf{j}}

and

\mathbf{B}=B_0\hat{\mathbf{j}}

. A particle of specific charge

\alpha

is released from the origin with velocity

\mathbf{v}=v_0\hat{\mathbf{i}}

. The quantities

E_0

B_0

, and

v_0

are constants. The path of the particle (a) is a circle (b) is a helix with uniform pitch (c) is a helix with non-uniform pitch (d) is a cycloid
