Question

1.) Consider a positive charge placed at point P. Based on the equipotential diagram, will this charge naturally want to move to the left or to the right? Does the electric field point to the left or to the right? Based on your answer, which conductor, I or II, has the +10 ?C and which has the -10 ?C charge? Explain your answers.

2.) Estimate the strength of the electric field at point P. Assume that one

Consider a positive charge placed at point P. Based on the equipotential diagram, will this charge naturally want to move to the left or to the right? Does the electric field point to the left or to the right? Based on your answer, which conductor, I or II, has the +10 ?C and which has the -10 ?C charge? Explain your answers. Estimate the strength of the electric field at point P. Assume that one 'box' of the graphing-paper grid corresponds to a length of d = 1 cm. This pair of conductors acts as a capacitor. What is the capacitance of this capacitor?

Explanation / Answer

1.) Consider a positive charge placed at point P.

Based on the equipotential diagram, will this charge naturally want to move to the left or to the right?

to the right, because a positive charge moves from higher electric potential to lower electric potential


Does the electric field point to the left or to the right?

To the right; because electric field points from higher electric potential to lower electric potential


Based on your answer, which conductor, I or II, has the +10 ?C and which has the -10 ?C charge? Explain your answers.

I: +10 uC

II: -10 uC

Because electric field goes from positive charge to negative charge


2.) Estimate the strength of the electric field at point P. Assume that one
