1. The density of a solid ball is to be determined in an experiment. The diameter of the ball is measured with a screw gauge, whose pitch is 0.5 mm and there are 50 divisions on the circular scale. The reading on the main scale is 2.5 mm and that on the circular scale is 20 divisions. If the measured mass of the ball has a relative error of 2%, the relative percentage error in the density is

An electron (mass 𝑚 and charge −𝑒) is placed at point A (Figure 1, 𝑧 ≪ 𝑅). What is the force acting on the electron? Looking at the expression of the force, determine the sign of 𝑞 so that the resulting motion would correspond to oscillations. The moving electron does not influence the charge distribution on the ring.

An electron is placed at point B (Figure 1, 𝑟 ≪ 𝑅). What is the force acting on the electron? Looking at the expression of the force, determine the sign of 𝑞 so that the resulting motion would correspond to harmonic oscillations. The moving electron does not influence the charge distribution on the ring.
