2. (a). Three forces that act on a particle are given by F1 = (20 i – 36 j + 73 k) N, F2 = (-17 i + 21 j – 46 k) N, and F3 = (-12 k) N. Find their resultant vector. Also find the magnitude

of the resultant to two significant figures.

(b). A vector has an x- component of -25.0 units and a y- component of 40.0 units. Find

the magnitude and direction of the vector.​

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?
