Particle 1 with mass \(m\) and positive charge \(+q\), and Particle 2 with mass \(4m\) and positive charge \(+2q\), are each accelerated from rest through the same electric potential difference \(\Delta V\). Upon exiting the accelerating region, each particle horizontally enters a region between two parallel plates of length \(L\) that maintain a uniform vertical electric field \(E\). Which of the following is the ratio \(y_2/y_1\) of the vertical deflection of Particle 2 to that of Particle 1 as they exit the region between the plates?
