WebSection Summary. Electric potential of a point charge is. V = k Q r. V=\frac {kQ} {r}\\ V = rkQ. . . Electric potential is a scalar, and electric field is a vector. Addition of voltages as numbers gives the voltage due to a combination of point charges, whereas addition of individual fields as vectors gives the total electric field. WebScience Physics Charge Q acts as a point charge to create an electric field. Its strength, measured a distance of 30 cm away, is 40 N/C. What is the magnitude of the electric field strength that you would expect to be measured at a distance of ... a. 60 cm away? b. 15 cm away? c. 90 cm away? d. 3 cm away? c. 45 cm away?
Potential Energy of Point Charges
WebElectric Potential Energy. Potential energy can be defined as the capacity for doing work which arises from position or configuration. In the electrical case, a charge will exert a force on any other charge and potential energy arises from any collection of charges. For example, if a positive charge Q is fixed at some point in space, any other ... WebIf a point charge + q is taken first from A to C and then from C to B of a circle drawn with another point charge + q at the centre, then work WAC and WCB are obtained.
