Use the following constants if necessary. Coulomb constant, k = 8.987 × 10º N · m² /C¥acuum permitivity, en = 8.854 × 10-12 F/mMagnetic Permeability of vacuum, µo = 12.566370614356 × 10¬7 H/rMagnitude of the Charge of one electron, e = -1.60217662 x 10 1º CMass of one electron, me = 9.10938356 × 10 31 kgUnless specified otherwise, each symbol carries their usual meaning. For example, µCmeans micro coulomh Say you have 3 charges q1 = 24, q2 = 27, q3 = -26cated at (0, 13) (7, – 13)and (6, –20}espectively. Now, say you choose four random points on the xyplane denoted by p1 (0, 7) p2 (15, –16) p3 (-5, – 16ànd p4 (0, 13). Note that, all charges are in nano coulombs. And all coordinates are in centimeters. Given this information, answer the following questions: a)Calculate the relative position vector that points from p4 to q2. x component of the vector Give your answer up to at least three significance digits. m y component of the vector Give your answer up to at least three significance…

Notice that cyclotron angular velocity we = do COS is a negative constant, i.e. in the figure the particle is circulating clockwise. 3. Consider a charged particle, q, in the presence of a magnetic field B with velocity i = it + üz = ü + ij at position relative to origin experiencing a magnetic force qü x B. From the second law it follows that the kinetic energy of the particle remains constant[ see figure 3] : d mv2 m[v² + v?] du - 0 = dt (a) : qü x B m ä - i [gữ x B] = ū.
