Use the diagram to label the following configurations.

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

more than, less

less than, more

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
