Problem 1 –Two isotopes of uranium, 235 U ( m = 3.90×10 25 kg) and 238 U ( m = 3.95×10 25 kg), are sent into a mass spectrometer with a speed of 1.05×10 5 m/s, as shown below. Given that each isotope is singly ionized, and that the strength of the magnetic field is 0.75 T, what is the distance d between the two isotopes after they complete half a circular orbit?

Problem 2 –A conducting rod of length L and mass m is suspended from the ceiling by two thin wires in a uniform magnetic field B . When a current I is run thru the wires in the direction shown, the rod gets deflected. Derive an expression for the angle of deflection in terms of the other variables, and state the direction that the magnetic field must point. Front view

Unformatted text preview: Side view θ I I Problem 3 – A single circular loop of radius 0.23 m carries a current of 2.6 A in a magnetic field of 0.95 T. What is the maximum torque exerted on this loop? What angle must the plane of the loop make with the magnetic field if the torque on the loop is to be half its maximum value? Problem 4 – Two long, straight wires are oriented perpendicular to the page as shown in the figure below. The current in one wire is I1 = 3.0 A, pointing into the page, and the current in the other wire is I2 = 4.0 A, pointing out of the page. Find the magnitude and direction of the net magnetic field at point P. 5.0 cm • P 5.0 cm X • I 1 = 3.0A I 2 = 4.0A...
