Solution 1
-
a) Both A and R are true and R is the correct explanation of A The electrostatic force does indeed increase as the distance between the charges decreases, and this is because the force is inversely proportional to the square of the distance between them.
-
a) Both A and R are true and R is the correct explanation of A The Coulomb force between two point charges does depend on the dielectric constant of the medium between them, and this force does indeed vary inversely with the dielectric constant.
-
a) Both A and R are true and R is the correct explanation of A The charge given to a metallic sphere does not depend on whether it is hollow or solid because the charge resides only at the surface of the conductor.
-
a) Both A and R are true and R is the correct explanation of A A comb run through dry hair can indeed attract small bits of paper, and this is because the molecules in the paper get polarized by the charged comb, resulting in a net force of attraction.
-
a) Both A and R are true and R is the correct explanation of A A proton placed in a uniform electric field does tend to move along the direction of the field, and this is because it experiences a force in that direction.
-
a) Both A and R are true and R is the correct explanation of A The electric field at the surface of a charged conductor is always normal (perpendicular) to the surface at every point, and this is because the electric field gives the magnitude and direction of the electric force experienced by any charge placed at any point.
