A -10.0 nC point charge and a +20.0 nC point charge are 15.0 cm apart on the x-axis. a. What is the electric potential at the point on the x-axis where the electric field is zero? b. What is the magnitude of the electric field at the point on the x-axis, between the charges, where the electric potential is zero?
The electric potential at the x-axis point is 103 V
The magnitude of the electric field at the x-axis point is
As the equation of the electric field of a point is
The electric potential value
As per the figure
Applying all values in the above equation
Applying the value of ,
A capacitor with plates separated by distance is charged to a potential difference . All wires and batteries are disconnected, then the two plates are pulled apart (with insulated handles) to a new separation of distance .a. Does the capacitor charge change as the separation increases? If so, by what factor? If not, why not?b. Does the electric field strength change as the separation increases? If so, by what factor? If not, why not?c. Does the potential difference change as the separation increases? If so, by what factor? If not, why not?
FIGURE Q25.6 shows the electric potential along the x-axis.
a. Draw a graph of the potential energy of a charged particle. Provide a numerical scale for both axes.
