In fig, two particles, each of charge -q are arranged symmetrically about the y-axis, each producing an electric field at point P on the y-axis. . (a) Are the magnitudes of the fields at P equal? (b) Is each electric field directed towards or away form the charge producing it ? (c ) Is the magnitude of the net electric field at P equal to the sum of the magnitudes E of the two field vectors (is it equal to 2E)? (d) Do the x-components of those two field vectors add or cancel? (e ) Do their y-components add or cancel? (f) Is the diretion of the net field at P that of the canceling components or the adding components? (g) What is the direction of the net field? |

Answer» (a) yes. (b) toward (c ) No, it is less than 2E. (d) Cancel (e ) Add (f) Adding components (g) Negative y. |
