You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?

Which compound is held together by the electrostatic force between two ions? a. co2 b. cci4 c. h2s d. mgf2
