Hello. I need the answer to the following questions.

1)

Q2 V? Q1 X2 X3 X1 Two charges Q1 = 4 /C and Q2 = -3.6 /C are located on the x-axis at x1 = -70 m and X2 = 83 m. What is the electric potential (V) at X3 = 37 m? (Please note: the charge is given in micro-Coulomb. The symbol in front of the C should be a Greek letter mu.)The electric dipole moment is dened as IT : qd , where d is the vector that points from the negative charge to the positive charge and g is the magnitude of either charge. For the water molecule shown here, the angle between the two 0-H bonds is 105 degrees and the length of each bond, r, is 1.62e-10 m. Assuming each 0-H bond consists of 1 electron and 1 proton, what is the magnitude off for either bond? Tries was What is the magnitude of the net dipole for the entire molecule? : The electric attractions and repulsions of the ions on the surface of complex molecules play a critical role in many biochemical reactions. An interesting component of some of these processes is that chemical reactions or electron transfers result in a change of the shape of a molecule, exchanging chemical energy for electrical energy, and resulting in a different surface conguration and therefore different interactions. In this problem we Will explore the effect ofa change of conguration of a molecule on the force between it and an ion in a neighboring molecule. Consider the electric force between four ions on the surface of two large molecules as shown in the figure at the right. The heavy black lines running out of the frame indicate bonds to other atoms in the molecule that we will not consider here. The purple ion in the molecule on the right has a charge +8, the red ion in the molecule on the left has a charge 722, and the two green molecules in the molecule on the left each have charges +e. A schematic diagram of these ions is shown below indicating relative distances. (a) Consider the followmg image. Qualitatively (without doing a calculation), would you expect the force of the ions (ABC) on ion D to be attractive or repulsive? Incorrect The force of the ions (ABC) on ion D is repulsive. Correct: The force of the ions (ABC) on ion D is attractive. You are correct. Your receipt no. is 164-73 @ W (p) Now do the calculation to find the net force between (ABC) and D. Express your result as a multiple of the combination 7 1:622 7 d2 l) 13 ChronieUS System - aom electron is moved from point At point B in a uniform electric field and gains 1.92x10-15 j of electrostatic potential energy.
