As the charge of Object A is doubled, the electric field strength created by object A increases by a factor of 2.Group of answer choicesTrueFalse

When you have two charges moving closer together, what happens to the electric force between them?Group of answer choicesStays the sameGets strongerBecomes zeroGets weaker

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.

The electric force generated by two point charges separated by Distance A is 4 times greater than the electric force generated when separated by Distance B.  How does Distance A compare to Distance B?A.Distance A is longer by a factor of 2.B.Distance A is longer by a factor of 4.C.Distance A is shorter by a factor of 2.D.Distance A is shorter by a factor of 4.

Which of the following changes would increase the force between two charged particles to 9 times the original force?A.Increasing the distance between the particles by a factor of 3B.Decreasing the distance between the particles by a factor of 3C.Increasing the amount of charge on each particle by a factor of 9D.Decreasing the amount of charge on one of the particles by a factor of 9
