Solution

Solution for If the magnetic field is parallel to the positive  y-axis and the charged particle is moving along the positive  x-axis (Fig.). Which way would the Lorentz force be for an electron (negative charge).
According to screw rule or right-hand thumb rule we can say that, the velocity  \(v\)  of particle is along the  \(x-\) axis. While  \(B\)  the magnetic field is along the  \(y-\)axis. So  \(v \times B\) is along the  \(z-\)axis. So, for electron it will be along  \(z-\)axis.
