Expert Solution & Answer

Answer to Problem 1P

Correct choice is (b)

Explanation of Solution

Introduction:

Magnetic force on a moving charged particle moving through a magnetic field region is given as

Fb→=q(v→×B→)

Clearly, the direction of deflection of the charged particle is given by the direction of the cross-product of velocity of the charged particle and magnetic field vector.

Direction of deflection of the electron is same as the direction of the magnetic force on it. For a positive charge, the direction of deflection is same as you get for the magnetic force using right hand rule but for a negative charge, the direction of deflection is opposite to the direction of magnetic forceyou will get using right hand rule.

Conclusion:

Hence, correct choice of path is (b)

An Electron Evaporator. Electron beams are sometimes used to melt and evaporate metals in order to deposit thin metallic films on surfaces (similar to gold plating). One method is to put the material to be evaporated (called the "target") into a small tungsten cup (a crucible that has a very high melting point) and direct a beam of electrons at the target. Your team has been given the task of designing an electron-beam evaporator. The crucible is a cylinder, 2.0 cm in diameter and 1.5 cm in height, and contains a small target of pure nickel (Ni). The electrons are accelerated through a potential difference of V = 1.20 kV, and form a beam that originates below the crucible, exactly D = 4.00 cm off its center, in the +x direction (see the drawing).
