Coulomb's Law (CP)

If each of the charges doubles, what happens to the force?

• Quadruples
• Doubles
• Stays the same
• Reduced by half

If the distance doubles, what happens to the force?

• Reduced by half
• Reduced by 1/4
• Stays the same
• Quadruples

If the distance is reduced by half, what happens to the force?

• Quadruples
• Doubles
• Triples
• Reduces by half

Electrostatic force F is directly proportional to:

• r^2 (distance squared)
• q1 (charge 1)
• q2 (charge 2)
• both q1 and q2

When distance increases, electrostatic force ____________; we call this relationship ____________ proportional

• decreases;directly
• decreases;inversely
• increases;inversely
• increases;directly
