The diagrams show the trajectories of two particles with the same mass and charge and which initially have the same velocity \(u\), as shown. The subsequent motion of each particle is determined by its properties and by its interaction with the field in which it is moving.
\(X\) and \(Y\) represent the landing points in Figures \(\text{I}\) and \(\text{II}\).
Which row of the table shows the correct paths of the particles if the mass of each is increased by the same amount and they are given the same initial velocity \(u\) ?
