A Charge Floating Between Plates
Difficulty: Easy · Topics: Electric Field, Electric Force, Equilibrium
Qoplamalar orasida muallaq turgan zaryad
As shown, the potential difference between two plates is V = 3 V and the distance between them is d = 2 cm. A particle with charge q = -0.4 C is at rest under gravity and the electric force.
