• Electrolysis

The fundamental charge (charge of an electron or proton) is approximately:

• 1.6 \times 10^{-19} C

• 9.1 \times 10^{-31} C

• 6.02 \times 10^{23} C

• 3.2 \times 10^{-19} C

Two like charges are placed near each other. They will:

• Attract each other

• Repel each other

• Neither attract nor repel

• First attract, then repel

Which of the following materials is an insulator?

The charge on a body is always an integral multiple of:

• 1.6 \times 10^{-18} C

• 1.6 \times 10^{-19} C

• 9.1 \times 10^{-31} C

• 6.63 \times 10^{-34} C

Coulomb’s law states that the electrostatic force between two charges is:

• Directly proportional to the square of the distance between them

• Inversely proportional to the distance between them

• Inversely proportional to the square of the distance between them

• Independent of the distance between them

If the distance between two charges is doubled, the electrostatic force between them becomes:

• Four times

• Half

• One-fourth

• Double

The process of sharing charges by touching a charged body to a neutral body is called:

• Conduction

• Polarization

• Grounding

The electric field due to a point charge is given by:

• E = k \frac{q}{r^2}

• E = k \frac{q}{r}

• E = k \frac{q}{r^3}

• E = k q r^2
