Charge on Conductors: an Irregular Conductor Carries a Surface Charge

question 14

Essay

Charge on conductors: An irregular conductor carries a surface charge density of -6.75 µC/m² at and in the vicinity of a point P on the surface. An electron is released just above P outside the conductor. What are the magnitude and direction of its acceleration the instant after it is released? (ε₀ = 8.85 × 10^-12 C²/N ∙ m², e = 1.60 × 10^-19 C, ^m_el = 9.11 × 10^-31 kg)
