Q1). A particle, of mass 2.48×10-25 kg, has the samecharge as an electron, but positive, moves in a circle of radius5.82m at constant speed, due to the action a magnetic field of0.00316 Tesla, directed perpendicular to the plane of the circle.What is the speed of the particle in m/s?
Q2). A 19.2m wire is at an angle of 11.4 degrees to magneticfield of 0.00376 T. The force on it is 2.2N. Find the currentcarried by the wire (in Amperes).
Q3). A current of 41.9 Amps in a wire loop results in a maximumtorque of 60.6Nâ‹…m. The loop encloses an area of 21.5 m2. Compute the magnetic field the wire loop is affected by in Tesla.Assume magnetic field is uniform.
Q4). A loop of wire has a resistance 431 Ohms and an area of4.93 m2 . The wire loop is located in a magnetic fieldwhich is perpendicular to the plane of the loop. The magnetic fieldhas the following time dependence: B=B0 exp(-b*t) wheret is time. b =0.595Hz.The current is 0.00708 Amps at time 0.885s.Find B0 in units of Tesla. (Note that both B andB0 are magnitudes i.e. positive.)
Q5). A 4.84m rod moves at 7.84 m/s in a plane perpendicular to auniform magnetic field. The length of the rod is orientedperpendicular to the velocity vector and the magnetic field. Thepotential difference between the ends of the rod is 15 Volts. Whatis the magnetic field magnitude (in Tesla).
