Which property of the field lines explains the attraction between unlike charges?

Which of the following is true of electrical lines? (a)Like charges attract unlike charges repel. (b)Electrical forces are produced by electrical charges. (c)Positive and negative charges can combine to produce a third type. (d)Electrical forces are weaker than gravitational forces.

Give the general properties of field lines.

Potential difference is a field property. Potential energy is the interaction energy of charge configuration:- If they are not the same, then define them.

Potential difference is a field property whereas Potential energy is the interaction energy of charge configuration.State how they are related.

Assertion : The solution of carbon tetrachloride in heptane shows positive deviation from Raoult's law. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution.

Name the law which explains the relation between current and the magnetic field produced by the current.

Assertion : The boiling point of chloroform-acetone solution is larger than expected from ideal behaviour. Reason : The forces of attraction between unlike molecules are stronger than those between like molecules in the solution. This results in lower vapour pressure as compared to an ideal solution which is responsible for the higher boiling point.
