Coulomb’s Law Worksheet
1. Riley, the dog, walks around with 1.23 x 105 electrons. How much charge
is she carrying around?
2. A negative charge of -200 µC and a positive charge of 800 µC are
separated by 0.30 m. What is the force between the two charges? Is this
force attractive or repulsive?
3. A negative charge of -6.0 x10-5 C exerts an attractive force of 65 N on a
second charge 0.50 m away. What is the magnitude of the second
charge?
4. A force of -4.4e3 N exists between a positive charge of 8.0e-4 C and a
negative charge -3.0e-4 C. What is the distance that separates the
charges?
