An electron, moving along the x-axis with an initial energy of 100eV, enters a region of magnetic field B→=(1.5×10⁻³T)k^ at S (See figure). The field extends between x=0 and x=2cm. The electron is detected at the point Q on a screen placed 8cm away from the point S. The distance d between P and Q (on the screen) is :(electron's charge =1.6×10⁻¹⁹C, mass of electron =9.1×10⁻³¹kg)<p></p>
