Extract information about electric charges and fields from the provided text.
Understand the Problem
The image provides a summary of key concepts and formulas related to electric charges and fields, including definitions of physical quantities, important formulas, and principles such as Coulomb's law and the superposition principle.
Answer
Electric charges can be frictional, additive, and conserved. Electric field strength is given by E = (1 / 4πε₀) * (q / r^2), measured in V/m or N/C.
Electric charges: Charges can be frictional, additive, and conserved. The charge of an electron is -1.6 x 10^-19 C, and a proton is +1.6 x 10^-19 C. Electric field: The electric field strength due to charge q is E = (1 / 4πε₀) * (q / r^2). The unit of electric field is V/m or N/C.
