What is a spectrometer? What is the use of a spectrometer?

Use the following constants if necessary. Coulomb constant, k=8.987×109N⋅m2/C2. Vacuum permitivity, ϵ0=8.854×10−12F/m. Magnetic Permeability of vacuum, μ0=12.566370614356×10−7H/m. Magnitude of the Charge of one electron, e=−1.60217662×10−19C. Mass of one electron, me=9.10938356×10−31kg. Unless specified otherwise, each symbol carries their usual meaning. For example, μC means microcoulomb A current carrying wire(wire-1) with i1=14Amperes is placed at the origin on the Y-Z plane. Another current carrying wire(wire-2) with i2=14Amperes is placed l=11m distance apart on the Y-axis. The point P2 is l1=8m from the wire-1. P1(0,8,−13), P2(0,8,0) and the point P3(0,8,10) are on the same line. The direction of the current is given in the figure. Step 1: Consider a wire-1 only.  a)Calculate magnetic field at P1 x component, y component & z component Calculate the magnetic field at P2 x component, y component & z component Step 2:Consider both wires b)Now what is the net magnetic…

12.57×10-7 Tesla is not a valid option of the answers available to choose.

A proton beam accelerated by a 100 kV potential difference enters a region where there is a 0.1 T magnetic field at right angles to the beam. i) Calculate the radius of curvature of the beam in the magnetic field region. ii) Sketch the trajectory of the proton beam and state how the velocity of the protons has been affected by the magnetic field.
