a) Is the electric field strength at point A larger, smaller, or equal to the field strength at point B? Explain your reasoning. b) From the information in the figure, estimate the electric field at point D.
The figure to the right shows a series of equipotential curves.
a) Is the electric field strength at point A larger, smaller, or equal to the field strength at point B? Explain your reasoning.
b) From the information in the figure, estimate the electric field at point D.
a)
The equipotential curves are the curves along which the electric potential does not change and the electric field is normal to it.
The electric field’s strength is greater where the equipotential lines are closer or denser.
From the given figure it can be observed that the equipotential lines are closer at B than at point A.
Thus, the electric field’s strength at point A is smaller than the field’s strength at point B.
