6.7 A circular loop of area of A=20cm2 is in the presence of a uniform amplitude but sinusoidal frequency of 300MHz signal. When oriented for maximum received signal, the loop develops a peak emf value of 30mV. What is the peak value of B⃗ of the incident radio frequency wave.

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
