1. In one type of mass spectrometer, ions having the same velocity move through a uniform magnetic field. The spectrometer is being used to distinguish ¹²C⁺ and¹⁴C⁺ ions. The ¹²C⁺ ions move in a circle of diameter 44.6 cm.Use these atomic mass values: ¹²C, 12.0u; ¹⁴C, 14.0u.

What is the diameter of the orbit of ¹⁴C⁺ ions?

_____________ cm

2. A 17.2 cm 26.1 cm rectangular loop of wire carries 1.00 A of current clockwise around the loop. Amagnetic field of 1.30 T actsin the plane of the loop, 60.0 below the +x-axis.
