21.65 -. If we rub a balloon on our hair, the balloon sticks to a wall ceiling. This is because the rubbing transfers electrons from our hair to the balloon, giving it a net negative charge. When the balloon is placed near the ceiling, the extra electrons in it repel nearby electrons in the ceil- ing, creating a separation of charge on the ceiling, with positive charge closer to the balloon. Model the interaction as two point-like charges of equal...
Two balloons have equal and opposite charges. Balloon one has N= 106 excess electrons
Two balloons have equal and opposite charges. Balloon one has N= 106 excess electrons. The balloons are separated by d= 1.8 m and each electron has a negative charge of e = 1.602 * 10-19 C. Part (a) What is the charge on balloon two, Q2, in C? Part (b) What is the magnitude of the force in N) of balloon one on balloon two using the variables provided and the Coulomb constant k (k = 8.988 x 109 N m2/C2).

(8c21p7) Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of -0.4304 N when separated by 50 cm, center-to-center. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.1165 N. What were the al charges on the spheres? Since one is negative and you cannot tell which is positive or negative, there are two solutions. Take the absolute value...

A pair of electrically charged objects attract each other with a force of 1 N when they are a distance of 4 m apart. If their charges stay the same, then what will be the attractive force between them when they are 12 m apart? 0.33 N 0.11 N 9.0 N 3.0 N 0.056 N Remember that the electric force F between two charges Q1 and Q2 is given by: F kQ1Q2/r Therefore, the electric force F is INVERSELY proportional...

Two point charges of equal and opposite charge ±10−8 C sit a distance of 20 cm apart. What is the strength of the force they exert on each other? If one of the point charges is sitting on a table and has a mass of .010 kg, how close must the second charge be to lift the charge up off the table? What is the electric field strength required to lift the charge of the table? I got the strength...
