(a) Explanation The diagram for the system is given by figure 1. Write the expression for the Coulombs constant. k = 1 4 π ε 0 (I) Here, k is the coulomb’s constant and ε 0 is the permittivity of free space. Write the expression for the electric field by using (I). E = λ 2 π ε 0 r = 2 k λ r (II) Here, E is the electric field, λ is the charge per unit length and r is the distance. Write the equation for potential difference. ( V B − V A ) = − ∫ A B E . d r (III) Here, V B , V A are the potentials at point A and B. Conclusion: Substitute, 2 k λ r for E in Equation (III) to find ( V B − V A ) (b) To determine The magnitude of electric field.

Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

4 Problem 4) A particle is being pushed up a smooth slot by a rod. At the instant when 0 = rad, the angular speed of the arm is ė = 1 rad/sec, and the angular acceleration is = 2 rad/sec². What is the net force acting on the 1 kg particle at this instant? Express your answer as a vector in cylindrical coordinates. Hint: You can express the radial coordinate as a function of the angle by observing a right triangle. (20 pts) Ꮎ 2 m Figure 3: Particle pushed by rod along vertical path.
