Problem

A charged particle of unit mass and unit charge moves with velocity

\mathbf{v} = (8\hat{i} + 6\hat{j})

m/s in a magnetic field of

\mathbf{B} = 2\hat{k}

T. Choose the correct alternative (s). a. The path of the particle may be

x^2 + y^2 - 4x - 21 = 0

b. The path of the particle may be

x^2 + y^2 = 25

c. The path of the particle may be

y^2 + z^2 = 25

d. The time period of the particle will be 3.14 s
