State the Properties of Electric Field. |
|
Answer» Properties of Electric Field : (i) The field exists at every point in three-dimensional space. (ii) For a positive charge, the electric field will be directed radially outwards from the charge. On the other hand, if the source charge is negative, the electric field vector, at each point, points radially inwards. (iii) Since the magnitude of the force F on charge q due to charge Q depends only on the distance r of the charge q from charge Q, the magnitude of the electric field E will also depend only on the distance r. Thus at equal distances from the charge Q, the magnitude of its electric field E is same. (iv) Electric field is a vector quantity whose magnitude and direction are uniquely determined at every point in the field. |
