Fundamentals of Electromagnetics with Engineering Applications
- Goal:The intent of this problem is to understand how electrostatic models can be used outside of electrical engineering. This basic model is used to understand chemical reactions, bonding, and other forms of atomic processes. It also shows you the strength of electrostatic forces in an atom. The Thomson model of a hydrogen atom is a sphere of positive charge with radius Ro with an electron (a point charge) at its center. The total positive charge equals the electronic charge q. What is the force of attraction between an electron at a distance R from the center of the sphere of positive charge? OOOO qR 4π€, Ro O q²R 3πEO q²R 4π€, Roarrow_forwardIn the figure below, analytically determine the electric field at point P. Where q1 = q2 = q. 92 2. -3 -2 -1 1. -1 -2. 91 Once you determine the electric field analytically, answer: What would be the force on a test charge Q located at point P? Justify your answer. In case the sign of both charges is exchanged to a negative sign, what would be the field on the point P in this case? Give as detailed an explanation as possible. Note: You do not need to redo the procedurearrow_forward1. Find the force on charge Q1, 20µC, due to charge Q2, -300µC, where Qı is at (0, 1, 2) m and Q2 at (2, 0, 0) m.arrow_forward
- Basic: You have two charges Q1=5x10-6 and Q2= -2.5x10-6 as shown in the figure; calculate the resulting force on an electron at point Parrow_forward2: we had equally like charges arranged in a pattern of of aclock face. There are 12 equally like charges arranged in a clock face patternof radius R. Determine then, if we were to bring a like charge from infinitedistance to the center.

- The Potential difference Vpo resulting from the work required to move a 10 nC charge from the origin to point P(I, 1, 0) against the static field E =5ax (V/m) is: Select one: a. -5 V b. 5 V c. None of these d. -5 nJarrow_forwardWhat is the force F on the 1.0 nC charge in the middle of Figure 2 due to the four other charges? Notice:Give your answer in component form(in x and y components). Along with calculations also write theory to help me understand,i have got stuck with different answers to this question,plz help me answering properly.arrow_forward5. Two point charges of 4 µC and 16 µC are separated by a distance of 14 mm. A point P is at a distance of 8 mm from the 4 µC charge and 6 mm from the 16 µC charge. Calculate the electric potential at P and electric potential energy of a charge of 10 µC at P?arrow_forward
- Consider the arrangement of the point charges shown below. Charge q1 has a value of 6.00 CC and charge q2 has a value of -1.00 CC . What will be the magnitude and direction of the force on the electron at the bottom if the other charges are held in place? a) The magnitude of the force on the electron will be: b) The electron will experience the force at an angle of: (note the +x-axis is defined as 0 degrees.arrow_forwardTwo equal charges of +8microC are separated by 1.6mm. Determine the force between the charges. Tell whether the force is attractive or repulsive. Determine the intensity of the electrical field produced by a charge of +5microC at a point P that is 3mm to the right. What is the value and nature of the force over a charge of -8microC situated at point P? Two charges of +16microC and -8microC are separated 10mm. Determine the intensity and direction of the electric field at point P situated right in the middle of the two charges (see figure).arrow_forwardWhen dealing with a point charge what is the most logical place to set V=0? At the charge's outside surfae. O The zero point is arbitrary so it doesn't matter. O At the charge's location. At r-1 m. At infinity.arrow_forward
