A –3.0 nC charge (on the left) and a +3.0 nC charge (on the right) are separated by some horizontal distance. The point P is a distance 5.0 mm away from each charge. The line from the negative charge (on the left) to point P makes a +25º angle with with the horizontal line between the two known charges. What is the magnitude of the net electric field at point P? (Hint: Make sure you can draw a diagram of...
A balloon rubbed against denim gains a charge of −6.0 μC. What is the electric force between the balloon and the denim when the two are separated by a distance of 3.0 cm? (As- sume that the charges are located at a point.) The value of the Coulomb constant is 8.98755×10 N·m /C . Include direction of the force. Answer in units of N.

A +3.0 nC charge Q is initially at rest a distance of 10 cm(r₁) from a +5.0 nC charge q fixed at the origin. Naturally, the Coulomb force accelerates Q away from q, eventually reaching 15 cm(r₂).The charge Q is repelled by q, thus having work done on it and losing potential energy. What is the work done by the electric field between r₁ and r₂? What is the change in the potential energy of the two-charge system from r₁...
