A small charged glass bead of weight 5.4 × 10⁻⁵N is initially at rest at point A in a vacuum. The bead then falls through a uniform horizontal electric field as it moves in a straight line to point B, as illustrated in Fig. 2.1. [Figure 2.1] The electric field strength is 1.3 × 10⁴ Vm⁻¹. The charge on the bead is –3.7 × 10⁻⁹C.
