1. A mass spectrometer uses an electric field of 9 500. V/m and a magnetic field of 0.095 0 T in its velocity selector. The same magnetic field is used in the spectrometer section.
a. Draw a diagram of the velocity selector. Show the direction of all fields and forces. Clearly derive an expression for the velocity of the charges particle which passes through undeviated.
b. Evaluate the expression for the velocity.
c. What is the radius of curvature of singly charged lithium ions of mass 1.162x10-26. Show all steps to final result.
A converging lens (f = 24.6 cm) is used to project an image of an object onto a screen. Find the two object distances
18 g of helium gas are placed in a cylinder with a movable piston. The gas is compressed very slowly from a state of ( p1 = 5.5atm, v1 = 32.7 × 10^3 m3) to a state of (p2 = 17atm, v2 = 11 × 10^3 m3 )
At (1,0) the voltage is 4.00V. At (3,0), the voltage is0.00V. If there is a steady, uniform electric field over this entire region, how much work is required to move an electron from the origin to (6,0)? (Coordinates are given in cm.)
