5. The electric and magnetic fields can be used together to perform measurements of the properties of charged particles. We explore this relationship here. An electron is traveling 4.1 x $10^5$ m/s in a region of space with uniform magnetic field perpendicular to its velocity. It experiences a magnetic force of 2.0 x $10^{-15}$ N. B V e T a. What is the magnitude in Tesla (as a positive number) of the magnetic field? b. You want to balance the magnetic-field force on the electron with an electric force. What electric field direction do you need to get an electric force opposite the direction of the magnetic force? c. You want to balance the magnetic-field force on the electron with an electric force. What electric field magnitude in N/C do you need to do this? d. What will be the path of the electron if this electric field is applied? e. What will be the path of the electron if this electric field is not applied? Remember that if the direction of the electron's velocity changes while the magnetic field stays in the same direction, the magnetic force will change direction.

The flange is made of carbon steel with a stainless steel lining (raised face) in the form of a ring. A flat asbestos gasket (Gasket factor = 2) of 1000 mm inside diameter and 1080 mm external diameter with 4 mm thickness is used to cover the raised face. Estimate the following: (i) Minimum bolt load under atmospheric and operating conditions in N. (ii) Bolt area in mm². Data given: Minimum design seating stress = 10.5 N/mm² Design pressure = 0.4 N/mm² Permissible stress = 52 N/mm² We need the answer in N for (i) and mm² for (ii).

A limited cycle has a compression ratio of 13, with 300 kJ/kg total heat added during the cycle. The pressure and temperature readings before isentropic compression is 95 kPa and 25C, and the heat added during cut-off process is 2/5 of the total. Calculate the mean effective pressure in kPa.

Select the correct answer in the following multiple choice statements. 1. In order to operate on the inelastic portion of the market demand curve, the cartel must be: \begin{itemize} \item Partial (or imperfect) \item Perfect (all firms participate) \item No cartel operates in that portion of the demand curve \item Both imperfect and perfect cartels operate there. \end{itemize} 2. A single-product Natural Monopoly is always sustainable when it is regulated with Ramsey pricing assuming that: \begin{itemize} \item Costs are sub-additive only \item Cost are sub-additive and concave \item Fixed costs are very small \item Ramsey pricing ensures sustainability irrespective of the costs shape. \end{itemize} 3. Bundling raises higher revenues than selling the goods separately when: \begin{itemize} \item Demands for two goods are highly positively correlated \item Demands for two goods are weakly positively correlated \item Demands for two goods are negatively positively correlated \item Goods are complements \end{itemize}
