Question

Wednesday Homework Problem 3.3 The dia- gram to the right shows the electric field lines for some charge distribution. The electric force vectors are drawn for a proton placed at points A through E. Only one of the vectors is correctly drawn. Which vector is correctly drawn? Select One of the Following (a) The vector at point A is correctly drawn. (b) The vector at point B is correctly drawn. (c) The vector at point C is correctly drawn (d) The vector at point D is correctly drawn. e) The vector at point E is correctly drawn.

Explanation / Answer

(a) vector A is correctly drawn.

Electric field E is tangential to the force line at any point of force line.

B and C are drawn perpendicular to force lines. E is opposite to force line direcgtion and D is in the field direction but horizontal not tangential to force line.

Hence only A is correct.
