The solar system is about 5 billion years old and completes one orbit around the center of the Milky Way in 240 million years. Therefore, we conclude that the solar system has completed a total of about ___ orbits around the galactic center.

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?
