A 10-liter container has 2 moles of oxygen at a pressure of 92 kPa. The effective speed (rms) of the oxygen molecules in the gas is: a) 534 m/s
b) 208 m/s
c) 375 m/s
d) 441 m/s

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?
