A region of space defined by \(x > 0\) contains a uniform magnetic field \(\vec{B}\) directed perpendicularly out of the page. Four positively charged particles are launched one at a time from the origin \((0,0)\) along the positive \(x\)-axis into the magnetic field region, as shown in the figure.

Particle	Mass	Charge	Initial speed
1	\(m_0\)	\(+q_0\)	\(v_0\)
2	\(m_0\)	\(+2q_0\)	\(2v_0\)
3	\(2m_0\)	\(+q_0\)	\(v_0/2\)
4	\(2m_0\)	\(+2q_0\)	\(v_0\)

Which of the following correctly ranks the dwell time \(t\), defined as the time spent inside the magnetic field region before exiting, for the four particles?
