Directions of the fields are indicated on field lines. Why are no directions indicated on equipotential lines? greatest 2、 For the dipole configuration, in what region(s) does the electric field have the intensity? Explain how you know from your map, and justify. Don't forget units (ce

Answer 1

Solution::

Arrows are not drawn i.e direction is not indicated on equipotential lines because no work is required to move a charge along an equipotential line. 2. Where the field lines are close together, the field is strongest, where the field lines are far apart the field is weakest. So, the intensity is strongest in Region - II. E^vector is inversely proportional to the square of the distance from the source. E = k q_1 q_2/r^2 implies E proportionalto 1/r^2 So, its magnitude decreases, as the distance from the source increases. E = Q/epsilon_0 A The electric field lines are constant and parallel inside the plates.
