- I need help with an explanation only on the question that asks what statements are correct. I think all statements are true except for for (I) is this correct? Please explain why. The sphere diagram is the attached as well.A 3*10°C charge is at (-1, 0). A -4*10°C charge is at (2, 0). (a) Calculate the field at the origin. (b) Calculate the voltage at the origin. (c) If an electron is placed at the origin, what force would act on it? What PE would it have? Draw the field lines and equipotentials for question 1. Make them as accurate as you can.Opgave 25.32: (a) A sheet with charge Q uniformly distributed over its area A is surrounded by a dielectric. Show that the sheet creates a uniform electric field at nearby points and derive an expression for the magnitude of the field. (b) Two large sheets of area A, carrying opposite charges of equal magnitude Q, are a small distance d apart. Show that they create a uniform electric field in the space between them and derive an expression for the magnitude of the field. (c) Assume the negative plate is at zero potential. Derive an expression for the potential at the positive plate. (d) Derive an expression for the capacitance of the pair of plates.
- A capacitor stores a separation of charge. To separate the charges on a capacitor, you have to move charges against where the E field wants to push them (the oppositely charges on the two plates are attracted and want to move together), so charging takes work. That work becomes stored energy -- just like carrying water up a hill so that you can let it roll down at a later time and turn a generator. The total amount of energy stored in a capacitor is ½|Q||ΔV|. We'll use this to determine the amount of energy stored in a cell membrane.In discussion, we found that a cell membrane maintains a potential difference of about 70 mV (0.07 V) between the inside and outside of the membrane. We also found that a 1 μm by 1 μm section of the membrane has a capacitance of about 1.75 10-15 F.1. What is the magnitude of charge on one side of the 1 μm by 1 μm section of the membrane?____ C2. What is the energy stored in the 1 μm by 1 μm section of the membrane?____ J3. For a cell with a radius of 10…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 thin wire carries uniform charge q and is shaped into a circle of radius R. What is the magnitude of the electric field at the center of the circle? (Hint: this one sho What is the value of the potential (referenced to 0 at infinity) at the center?
- using no mathematics, explain the physical mechanism by which bound surface charge arises in a dielectric material in an external electric field – how does it come about, what does it ‘look’ like?. A capacitor consists of two concentric spherical shells (inner radius a and outer radius b). The inner shell is at a potential of Vo and the outer shell is grounded. The dielectric between the two shells has the permittivity of E. (b) Calculate the surface charge density on the inner shell. Vo a O HI
