Physics 30 Unit D Assignment (/45marks) SHOW YOUR WORK, including starting equations, units, and proper sig-digs to receive full marks. 1. A group of physics students have been given a sample of unidentified charged particles. They are not given any hints about the particles, except that they appear in the fourth row of the periodic table (listed below). To determine the identity of the particle, they set-up an apparatus similar to J.J. Thomson's charge to mass ratio experiment. Their apparatus has the following settings: The students find the radius of curvature of the particles to be 98.057397 cm. From this information, determine the identity of the unidentified charged particle. (Hint: to find the mass of a single atom of any element, take the element's molar mass and divide by Avagadro's Number, NA = 6.022 x 1023 ) (Extra Hint: molar masses are given in g/mol) (6 marks)
