A person with a radio-wave receiver starts out equidistant from two FM radio transmitters A and B that are 11.0 m apart, each one emitting in-phase radio waves at 93.5 MHz . She then walks so that she always remains 50.0 m from transmitter B. (See (Figure 1).) Limit your solution to the cases where 50.0m≤x≤65.0m.
A) For what values of x will she find the radio signal to be maximally enhanced?
B) For what values of x will she find the radio signal to be cancelled?
