Understanding Coulomb's Law

What are the charges of Q1 and Q2 in the problem setup?

• Q1 is -6 micro Coulomb and Q2 is -14 micro Coulomb

• Q1 is 6 micro Coulomb and Q2 is 14 micro Coulomb

• Q1 is -14 micro Coulomb and Q2 is -6 micro Coulomb

• Q1 is 14 micro Coulomb and Q2 is 6 micro Coulomb

What is the direction of the force on charge 1 from charge 2?

• To the left

• To the right

• Upwards

• Downwards

Which constant is used in Coulomb's law to calculate the force?

• 9 x 10^9 N m^2/C^2

• 9 x 10^8 N m^2/C^2

• 8.99 x 10^9 N m^2/C^2

• 1 x 10^9 N m^2/C^2

Why do we not use the signs of the charges in the calculation?

• Because the signs are always positive

• Because we are only calculating magnitude

• Because the signs are irrelevant

• Because the signs are always negative
