The work done by an electric force in moving a charge from point $A$ to point $B$ is $2.70 \times 10^{-3} \mathrm{~J}$. The electric potential difference between the two points is $V_{A}-V_{B}=50.0 \mathrm{~V}$. What is the charge?

Key Concepts

Relationship Between Work, Charge, and Potential Difference

This key relationship is captured by the equation W = q(VA - VB), linking the work performed on a charge to the product of the charge and the potential difference between two points. It is essential for calculating any one of these quantities when the other two are known, thereby connecting energy concepts with electric fields.

Electric Potential Difference

This is the difference in electric potential energy per unit charge between two points in an electric field, measured in volts. It indicates the work required to move a unit charge from one point to another and is a central concept in understanding how energy is transferred in an electrostatic system.

Work Done by Electric Forces

This concept involves the amount of energy transferred when a charge is moved within an electric field by the work done by electric forces. The work done is directly related to both the magnitude of the charge and the electric potential difference through the equation W = q?V, which is fundamental in electrostatics.
