Question

3. What is the magnitude of the electric field (in N/C) at a distance of 1 mm from a single proton?

4. How strong is the attractive force (in N) between a glass rod with a 0.700 uC charge and silk cloth with a -0.600 uC charge, which are 12.0 cm apart?

6. Calculate the magnitude and direction of the electric field (N/C) due to a point charge of 2.00nC at a distance of 5.00 mm from the charge?

8.   How far apart (in mm) must two point charges of 75.0 nC be to have a force of 1.00 N between them?
