A conducting rectangular loop of mass M, resistance R, and dimensions w by l falls from rest into a magnetic field , as shown in the figure below. During the time interval before the top edge of the loop reaches the field, the loop approaches a terminal speed vT.(a) Write an expression for the terminal speed in terms of the given variables. (Use any variable or symbol stated above along with the following as necessary: g and B for )vT =(b) Describe and explain the relationship between vT and R.(c) Describe and explain the relationship between vT and B2.
