A platinum wire is used to determine the melting point of indium. The resistance of the platinum wire is 2 Ω at 20°C and increases to 3.072 Ω as indium starts to melt. What is the melting point of indium? (The temperature coefficient of resistivity for platinum is 3.9 × 10-3 (°C)-1)

A charged particle of mass 2 g is subjected to a 6 T magnetic field which acts at a right angle to its motion. If the particle moves in a circle of radius 20 cm at a speed of 5 m/s, what is the magnitude of the charge on the particle?

The drawing shows four situations in which a positively charged particle is moving with a velocity v→{“version”:”1.1″,”math”:”v→”} through a magnetic field B→{“version”:”1.1″,”math”:”B→”}. In each case, the magnetic field is directed out of the page toward you, and the velocity is directed to the right. In only one of these drawings is the magnetic force F→{“version”:”1.1″,”math”:”F→”} physically reasonable. Which drawing is it?

Superconductors can carry very large currents with no resistance. If a superconducting wire is formed into a solenoid of length 50 cm with 500 turns, what is the magnetic field inside the solenoid when the current is 10 kA?
