Could someone PLEASE help me with these physics questions?

(1) (12 pts.) Two identical small conducting Spheres are separated by 0.6 m. The Spheres carry different amounts of charge and each Sphere experiences an attractive force of 10.8 N. The total charge on the two Spheres is 24 n0. (a) What are the possible charges the spheres can have? (b) Next the two spheres are connected by a slender conducting wire (but nothing else is changed), which is then removed. In one or two sentences explain what happens to the charges when the Spheres are connected by the wire. (c) What is the nal electric force on each Sphere (magnitude and repulsive or attractive)? (2) (12 pts) Consider three very long, straight parallel wires each carrying a current of 4.00 A, directed out of the page as shown in the figure. The wires pass through the vertices of a right isoceles triangle of side 2.00cm. (a) Draw the magnetic field vector at point P (the midpoint of the hy- potenuse of the triangle) for the magnetic field due to each of the three wires. (b) What is the magnitude of the total magnetic field at point P (the mid- point of the hypotenuse of the triangle)? 4.00 A out O 2.00 P cm O 2.00 O 4.00 A out 4.00 A out cm FIGURE 1
