Using this relationship, we may find the sum of the particle's kinetic energy and electric potential energy. Formula used: \begin{aligned} & K=\frac{1}{2} m v^2 \\ & U=q V=\frac{k q Q}{\sqrt{z^2+a^2}} \\ & U_{\mathrm{f}}+K_{\mathrm{f}}=U_{\mathrm{i}}+K_{...
Find the potential in the interior of the sphere r = R = 1 if the interior is free of charges and the potential on the sphere is given by u ( R , \Phi ) = f ( \Phi ) = \operatorname { cos } 2 \Phi A ? - ("pi-minus") particle, which has charge -e, is at loc...
Calculations on a dipping contact in the presence of a line electrode have been previously reported for dip-angles ( θ 0) which are integral submultiples of π. The formulae derived in the present paper are valid for arbitrary angles of dip. It is shown that when π 0< π 2 there is...

Calculate E(x) for an electric potential (a) V(x) = - 104x; (b) V(x) = + 103x2. 12. Using results from Problem 11, calculate the work done by the electric field when a test charge qo moves from x = 2 m to x = 6 m. Then determine ΔV = V(6) - V(2) and compare...
The electric field control of magnetization is of significant interest in materials science due to potential applications in many devices such as sensors, actuators, and magnetic memories. Here, we report magnetization changes generated by an electric field in ferromagnetic Ga1−xMnxN grown by molecu...
In this chapter we tell about the history of drive systems, the types of drive systems, electronic drive technology, useful mechanical formulae, moment and torque of a motor and finally the run down test to determine the moment of inertia of a drive system. We start with a theoretical speed...
A formula for the multipole polarizabilities of a two-body bound complex formed by a central interaction potential has been derived and studied. To test, the developed $T$-matrix formalism has been applied to the calculation of the dipole, quadrupole and octupole polarizabilities of the hydrogen ...
