Question

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 87.0 MHz. She then walks so that she always remains 50.0 m from transmitter B (Figure 1). Limit your solution to the cases where x≥50.0m.

Part A:

For what values of xx will she find the radio signal to be maximally enhanced?

Part B:

For what values of xx will she find the radio signal to be cancelled?\

Thank you for the help!
