The particle at upper left has a charge q1 = 4.00 nC, the one at the lower left has a charge of q2 = 5.00 nC,and the one at lower right has a charge q3 = 6.00 nC. The rectangle's horizontal side has length x = 5.00 cm and its vertical side has length y = 3.50 cm. Three positive charges lie at three of the corners of a rectangle of horizontal side length x and vertical side length y < x. An charge labeled q1 is at the upper left corner. A charge labeled q2 is at the lower left corner. A charge labeled q3 is at the lower right corner. (a)What is the electric potential (in V) at the upper-right corner of the rectangle?

The remarkable adhesion might be due to static electricity. Gecko feet are covered with microscopic hairs. When these hairs rub against a surface, charges separate, with the hair developing a positive charge and negative charge forming below the surface. There is an attractive force between the separated charges. This is an effective means of adhering to a surface, but it comes at a cost: Two planes of charge are like two charged plates of a capacitor, which takes energy to charge. Doubling the amount of charge on each surface increases the attractive force, but also increases the energy required to separate the charge. By what factor does this energy increase?
