Q. In the determination of the volume of the irregularly shaped object, any air bubbles sticking to the surface of the object when it is submerged cause systematic error. Will this error give an experimental density that is too high or too low? explain
Q. An infinitely long conducting cylindrical rod with a positive charge lambda per unit length is surrounded by a conducting cylindrical shell (which is also infinitely long) with a charge per unit length of -2 lambda and radius r_1. What is sigma_inner, the surface charge density (charge per unit area) on the inner surface of the conducting shell?
A solid, rectangular iron bar measures .40cm by 1.0cm by 30cm. Find the resistance between each of the three pairs of opposing faces, assume the faces in question are quipotentials.
