Question

A charged particle is projected at a very high speed perpendicular to a uniform magnetic field. The particle will _____________ .

Options

• move along a circle

• move along a curve with increasing radius of curvature

• move along a curve with decreasing radius of curvature

• move along a straight line

Answer 1

move along a circle

 

If a charged particle is projected at a very high speed perpendicular to a uniform magnetic field, its mass will increase from m_o to \[m = \frac{m_o}{\sqrt{1 - \frac{v^2}{c^2}}}\] and its radius will increase.
