2. A slinky is stretched so that there is a gap of 0.95cm between each loop. The magnetic field at the center of the slinky is measured for a range of currents and a graph is plotted of B (in milli-Tesla) versus current I (in Amperes). The result is a straight line with a slope of 0.14 mT/A and an intercept of 0.024 mT. Determine the value of 4 from this result.
2. An electron starts from rest near the negative vertical plate of a set of parallel plates and accelerates towards the positive plate through 150 V. After crossing this distance the electron passes through a hole. The electron then moves through a horizontal set of parallel plates where the top plate is negative. These horizontal plates are separated by 2.0 cm and have a potential difference of 240 V. The electron passes through these plates undeflected due to a magnetic field perpendicular to the page. The electron then passes out of the plates where it is acted upon by the same uniform magnetic field. Find the magnitude and direction of the uniform magnetic field and the radius of the circular path of the electron. Draw the complete path of the electron.
