Acircular wire loop 51 cm in diameter has resistance 120 ω and lies in a horizontal plane. a uniform magnetic field points vertically downward, and in 25 ms it increases linearly from 5.0 mt to 55 mt. part a find the magnetic flux through the loop at the beginning.

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?
