We wish to place a small charged sphere at a distance of 5.0 m from a point in space such that the voltage at that point is 1.20 V. How much charge should be on the sphere (in nC)?
The formula for calculating charge is Q=V*d, where Q is the charge, V is the voltage, and d is the distance.
The unit of measurement for charge is Coulomb (C).
1.20V is already in Volts, so there is no need for conversion.
Voltage is the measure of potential difference between two points, while charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There is a direct relationship between voltage and charge, where an increase in voltage leads to an increase in charge.
The charge needed for a specific voltage is directly proportional to the distance. This means that as the distance increases, the charge needed to maintain a specific voltage also increases. This relationship is described by the formula Q=V*d.
