8. Three point-like charges are placed at the corners of an equilateral triangle as shown in the figure. Each side of the triangle has a length of 28.0 cm, and the point (B) is located half way between q2 and q3 along the side. Find the magnitude of the electric field at point (B).

3. An isolated system consists of two metal spheres, with sphere 2 having twice the radius of sphere 1. Both spheres are initially charged as shown in the initial figure. The two spheres are then brought into contact with each other so that charge, in the form of electrons, is transferred between them. The spheres are then separated as shown in the final figure, where they have unknown charges, q and q2. Since sphere 2 has twice the radius, it will have twice the amount of charge than sphere 1 in the final state. Find q, q and the number of electrons transferred between the spheres. Hint: The net charge of the two-sphere system is conserved, since it is an isolated system. initial electron transfer between spheres final 91 = +12.0 μC 9₁ = ? q2 = -3.00 μC 9₂ = ?
