1. An oil drop with a mass of 2.48 x10^-15kg is balanced between two parallel, horizontal plates 1.7cm apart, maintained at a potential difference of 260 V. The upper plate is positive. Calculate the charge on the drop in coulombs and as a multiple of the elementary charge. Determine whether there is an excess or a deficit of electrons.

2. Two waves with equal speeds have frequencies of this wave is 40 Hz. What is the ratio of their wavelengths?

3. A wave on a string has a frequency of 0.83Hz and a wavelength of 0.56m. Determine the wavelength when a new wave of frequency 0.45Hz is established on this string and the wave speed does not change.

In Millikan’s oil-drop experiment, one looks at a small oil drop held motionless between two plates. Take the voltage between the plates to be 2033 V, and the plate separation to be 2.00 cm. The oil drop (of density 0.81 g/cm3) has a diameter of 2.9 x 10-6m. Find the charge on the drop, in terms of electron units. You need to round your answer to the nearest integer.

A small sphere with mass 2.10 g hangs by a thread between two large parallel vertical plates 5.00 cm apart (Figure 1). The plates are insulating and have uniform surface charge densities +σ and −σ. The charge on the sphere is q = 8.30×10−6 C . What potential difference between the plates will cause the thread to assume an angle of 30.0∘ with the vertical?

Extract 1 Oil price changes “The oil price drop since June 2014 was due to supply and demand factors. USA oil production doubled between 2009 and 2015. Countries such as Algeria, Saudi Arabia and Nigeria used to export oil to the USA but now the USA produces more than enough oil to meet its own needs. Furthermore, in 2014 OPEC producers decided not to reduce production and as a consequence by August 2015 the oil price decreased 40%. Oil is...
