Question

Two point charges are on the axis. Charge 1 is +q and is located at z =-1.0 m; charge 2 is-2q and is located at 1.0 m. Part A Complete the explanation of the equipotential surfaces for this system, using figures (Figure 1) and (Figure 2), out to a distance of about 2.0 m from the origin and far from the origin. In each case, indicate the direction in which the potential increases. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. Words may be used more than once. Reset Help first In the figure, the potential surface is a valley near the-2q charge and a second near the +q charge Figure 1 of 2> decreasing In the form a singlecharge. Equipotential lines for locations very far from the two charges are drawn indicating the direction of figure, far away from the charges the two charges appear blended together to hill valley potential increasing In the figure, the equipotential lines are drawn near the charges, together with arrows +9 2q that indicate the direction of potential Submit -2 0 x (m)

Explanation / Answer

Here I am only completing the blanks with some explanation :

1) first, hill

2) second, increasing

3) first, increasing

Here In the first figure direction of potential is towards +ve charge and away from the negative charge so in both cases the potential will increase.

For second case also since charge is negative so magnitude wise potential will decrease but since q is - ve so overall it will increase.
