Two point-like particles separated by 7 cm have charges q1=4 nC and q2=1 nC. Note that the force felt by each charge due to the other is a vector and has both a magnitude and a direction. What is the magnitude of the force exerted on the charges due to the electromagnetic interaction, in μN (10-6 Newtons)?
You will get the second part of the exam when you hand in the first part to me. Open book, notes and all electronic devices, talk to anybody but me. As you take this part of the exam, you may sit at a table where the other personls) have this part of the exam already but don't go to the...
1. Calculate the magnitude of the electric field at the center of a square 42.5cm on a side if one corner is occupied by a −38.9μC charge and the other three are occupied by −26.5μC charges. Choose the correct direction of the electric field at the center of the square. 2. Choose the correct direction of the electric field at...
Nuclear power plants convert the energy released in fission reactions to electric energy. Consider one such power plant that generates 1.00 GW of electric power. The fission of each uranium-235 nucleus releases 200 MeV of energy. The power released by the fission reactions is converted to electric power with a 41.0% efficiency. How much uranium-235 per day, by mass in...
23 For distances z which are large compared to the charge separation d, the electric field of an electric dipole is given by Ē 2kqd -ý. If the charge is q = 4.77 mC, and the dipole separation is d = 1.33 um, what is the magnitude of the electric potential of the dipole at z = 28.4 cm, assuming...
In a nuclear fission reaction, a heavy nucleus splits into two lighter nuclei, whose subsequent motion is governed by electric force only. As the two nuclei start moving appart from one another, a) their kinetic energy keeps decreasing b) their acceleration keeps increasing c) their kinetic energy keeps increasing d) their electric potential energy keeps decreasing e) their electric potential...

2. A 2.0-m wire carries a current of 15 A directed along the positive x axis in a region where the magnetic field is uniform and given by Bx = 30 mT and By =-40 mT. Show that the resulting magnetic force on the wire is 1.5 N pointing into the paper. [Please show a diagram for the direction!] 4. Show...
