WebThe total charge between the two objects is +4e +4e before and after transfer, so charge is conserved. The electrons redistribute so the rod becomes less positively charged and the sphere becomes positively charged, and the protons remain fixed. [Are other scenarios for charge transfer?] Common mistakes and misconceptions WebWhen discussing the electric potential between two charges, it is important to specify whether the quantity in question is electric potential energy, measured in joules, or electric potential difference, measured in joules per coulumb (J/C). Thus, voltage is electric potential energy per charge.
WebSep 12, 2024 · The forces on the two charges are equal and opposite, so there is no net force on the dipole. However, there is a torque: (5.8.1) r → = ( d → 2 × F → +) + ( − d → 2 × F → −) (5.8.2) = [ ( d → 2) × ( + q E →) + ( − d → 2) × ( − q E →)] (5.8.3) = q d → × E →.
