A 100 gram resistive slider (thick line) moves without friction along a vertical U-shaped conducting track (thin line) that is 50 centimeters wide in a magnetic field of 5 Tesla as shown. The slider's resistance is 20 Ohms. It falls under the influence of gravity. What is the terminal velocity of the slider in meters/second? Assume it can reach terminal velocity before it falls off

  3. for me it was 3.2, I think data are variables.

    By the way, have you done question 4? because I did

    B=uo N/L I,

    I from the 3rd quest. but for "a big t" and N/L= loop density, but that wans't the aswer, any hint?
