A40.0-$kg$ body is moving in the direction of the positive x axis with a speed of 238 $m/s$ when, owing to an internal explosion, it breaks into three pieces. one part, whose mass is 7.0 $kg$, moves away from the point of explosion with a speed of 356 $m/s$ along the positive y axis. a second fragment, whose mass is 4.5 $kg$, moves away from the point of explosion with a speed of 357 $m/s$ along the negative x axis. what is the speed of the third fragment

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?
