 ===== Example: Electric Potential from a Negatively Charged Balloon ===== ===== Example: Electric Potential from a Negatively Charged Balloon =====
 Suppose we have a negatively charged balloon with total charge Q=−5.0⋅10−9 C. What is the electric potential (also called voltage) at a point P, which is a distance R=20 m from the center of the balloon? Suppose we have a negatively charged balloon with total charge Q=−5.0⋅10−9 C. What is the electric potential (also called voltage) at a point P, which is a distance R=20 m from the center of the balloon?
Line 12: Line 13:
 We assume P lies outside of the balloon. This is obvious, as P is a distance R=20 m away from the center of the balloon. We assume P lies outside of the balloon. This is obvious, as P is a distance R=20 m away from the center of the balloon.
