c) Alpha particles of charge. 2 e and mass m= 6,63x10-27 kg are emitted from a radioactive source at a speed of 1.63x10 m/s What magnetic field strength would be required to bend them into a circular path of radius 0.18 m(4). OO o OO O O d) A particle with charge q and momentum p, initially moving along the x-axis, enters a region where a uniform magnetic field B. Bok extends over a width xlas shown in figure. The particle is deflected a distance d in the + y direction as it traverses the field Determine (a) whether is positive or negative, and (b) The expression for the magnitude of its momentum p ((8)

 

 

 

Question 2: a) Ammeter and Voltmeter are used to measure the electric current and voltage in an electric circuit, respectively. Ammeter should be connected in series and voltmeter should be connected in parallel. Explain why. What are the internal resistances of an ideal ammeter and voltmeter? (4) b) What will happen when charge particles are moving inside the magnetic field? List the different possible conditions when the force is zero even when the charge particles are inside the magnetic field.(4)
