Question

electeic field lines contracts lengthwise it shows (a) repulsion between same charges (b) attraction between oppoaite charges (c) no relation between force & attraction (d) electric filed lines do not move on a straight path​

Answer 1

Answer:

no relation between force & attraction

Explanation:

This explains attraction between two unlike charges. The lines of force have a tendency to expand laterally so as to exert a lateral pressure on neigh bouring lines of force. ... This explains repulsion between two similar charges.

Answer 2

Electric field lines contract lengthwise it showing the attraction between opposite charges.

The behaviour of Electric field lines:

• Electric field lines tend to constrict lengthwise while expanding laterally.
• The lateral expansion denotes repulsion between like charges, while the longitudinal contraction suggests attraction between unlike charges.

Why do electric field lines contract?

• Because electric field lines originate from a positive charge and travel to a negative charge, they contract longitudinally, indicating a force of attraction between opposite charges.

Therefore, electric field lines contracting lengthwise shows the attraction between opposite charges.
