← A small dipole has an electric field of size F at a point on its axis. A second point is on its equatorial line, at twice the distance from the centre. What is the size of the field at the second point?A small oil drop of radius 0.70 µm and density 850 kg/m³ hangs at rest in an upward electric field of 2.5 × 10⁴ N/C. How many excess electrons does it carry? Take g = 9.8 m/s² and e = 1.6 × 10⁻¹⁹ C. →
