Draw the pattern of electric field lines due to
(a) Negative charge
(b) Dipole (combination of positive and negative
charge)
(c) Two positive charges
Answers
Answer:
Two equivalent representations of the electric field due to a positive charge Q. (a) Arrows representing the electric field’s magnitude and direction. (b) In the standard representation, the arrows are replaced by continuous field lines having the same direction at any point as the electric field. The closeness of the lines is directly related to the strength of the electric field. A test charge placed anywhere will feel a force in the direction of the field line; this force will have a strength proportional to the density of the lines
Explanation:
The electric field lines comes out from a positive charge and goes into a negative charge .
fig. (1) shows closed field lines , which is impossible.
fig. (2) shows two positive charges , because field lines are coming out from both the charges and showing repulsion.
fig.(3) shows a single positive charge.
fig.(4) shows a uniform electric field from a positive plate to a negative plate.
fig.(5) shows a positive and negative charge , because field lines are coming out from a charge ( positive) and going into another charge (negative).
