Below are statements regarding the relationship of variables in Electric Force. Which among the statements is TRUE?Group of answer choicesThe force is inversely proportional to the square of the distance between the charges.The force is decreasing if the product of two charges is increasing.The force is increasing if the distance between two charges increases.The force is inversely proportional to the product of charges.

Coulomb's law states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects.Group of answer choicesTrueFalse

a) Both A and R are true and R is the correct explanation of Ab) Both A and R are true but R is NOT the correct explanation of A c) A is true but R is falsed) A is false and R is also false1. Assertion (A): The electrostatics force increases with decrease the distance between thecharges.Reason (R): The electrostatic force of attraction or repulsion between any two stationarypoint charges is inversely proportional to the square of the distance between them.2. Assertion (A): The Coulomb force between two points charges depend upon the dielectricconstant of the intervening medium.Reason(R): Coulomb’s force varies inversely with the dielectric constant of medium.3. Assertion(A): The charge given to a metallic sphere does not depend on whether it is hollowor solidReason(R): The charge resides only at the surface of conductor.4. Assertion (A): A comb run through one’s dry hair attracts small bits of paper.Reason(R): Molecules in the paper gets polarized by the charged comb resulting in net force ofattraction5. Assertion (A): A proton is placed in a uniform electric field, it tend to move along thedirection of electric field.Reason(R): A proton is placed in a uniform electric field it experiences a force.6. Assertion (A): Electric field at the surface of a charged conductor is always normal to thesurface at every point.Reason(R): Electric field gives the magnitude & direction of electric force ( ) experienced by anycharge placed at any point.

Which of the following is an effect of the electric force?A.Two positive charges repel each other.B.Two north poles repel each other.C.Two south poles are attracted to one another.D.Two negative charges are attracted to one another.
