Question

A portion of an electric field is shown below. Four locations within the field are marked with black dots and labeled a,b,c and d. draw a diagram showing only the four dots and then draw four vectors, one for each location, that estimate the electric field vector at each location (think of the force that would exerted o a positive charge +qo if it were placed at each of these locations.) your vectors should include both direction and relative magnitude, and you should explain your reasoning for each of the vectors.

l uiu lelative magnit plain your reasoning for each of the vectors you have draw eld lines in a region of space are shown in the diagram dicates the path ct that is bject only to the electric field represented by the field a postively charged particle

Explanation / Answer

the tangent on electric field lines at the required point will give the direction of electric field at that point .To calculate the magnitude we can calculate numerically also but distance from q to that point should be known.

here from the field line indicated one can get the relative strength of electric field by comparing the density of field lines at that point.

here at point B strength of electric field is highest and at D it is lowest.
