- V is the energy (in J) required to bring the two charges from infinite distance separation to distance r (in nm).Q1 and Q2 are the charges in terms of electrons.(i.e. the constant in the above expression is 2.31×10-19 J nm electrons-2) For a group of "point" charges (e.g. ions) the total energy of interaction is the sum of the interaction energies for the individual pairs. Calculate the energy of interaction for the square arrangement of ions shown in the diagram below.A negative charge Q equals -10 muC moves to the right in a uniform electric field if you electron gains 80 muJ of electric potential energy after moving 15 cm give the magnitude and direction of the electric fieldA small metal sphere carrying a net charge of Q = -2.00 uC is held stationary by insulating supports. A second small metal sphere with a net charge of Q 2 = +7.80 uC and mass 1.50 g is is held 0.8 m away from the center of the first sphere. Assume the two spheres can be treated as point charges and that you can ignore gravity. If the second sphere is released, how fast will it be traveling when it is 0.6 m away from the center of the first sphere?
- In this problem we explore dipoles as sources of fields and their interactions with other charges An induced dipole is a dipole (separated, opposite charges) whose charge separation and dipole moment are caused by the presence of an external electric field, often due to some other source charge. Often, the induced dipole moment is proportional to that electric field at the location of the dipole. For example, when a charged piece of tape is near your finger, the charges inside the neutral atoms in your finger move in response to the tape's field at the location of the finger, and each atom in the finger becomes a dipole. The closer the tape is to the finger, the stronger the tape's field, the more the charges move and the larger the dipole moments of the atoms in the finger. Mathematically, we can write this as p = aE, where p is the dipole moment, E is the strength of the electric field at the location of the dipole, and a is a constant that depends on the type of atom and gives the…A point charge of 33 uC is placed at a distance of 36 cm from another identical charge.
