Figure 5 shows two conducting rails 0.500 m apart with a 50.0 g conducting bar that slides on top of two rails. A magnetic field of 0.750 T is directed perpendicular to the plane of the rails and points upward. An external dry cell is connected to the rails supplying a voltage, V and a constant current of 1.00 A to the rail-bar system.
(a) Define a law of electrostatics in integral form that is used to compute the electrostatic field E due to a symmetric distribution of charge within a given volume. State the meaning of the terms in the defining equation. (b) A uniformly charged long cylinder of radius a and length L has total charge q inside its volume. What is the direction of the electric field at points outside the cylinder? Find the electric field inside and outside the cylinder. (c) Total charge q is distributed along a line of length L. Determine the electric field produced by the wire using Gauss’s law. Compare this result with the result in part (b).

Why there should be a relationship between electrical conduction and heat conduction in materials.
i. State the characteristic for the coherent sources.
ii. A light source is directed through two narrow slits separated at 5 x 10 m. Five meters away from the wall is a light detector which detects the interference pattern. It was found that the distance from the central peak to the first order interference fringes was 6 cm. What is the light source's wavelength?
iii. Recommend a suitable modification to the setup so that the distance between two consecutive fringes is increased.
