Two radio transmitters radiating in phase are located at point A and B, 250 m apart. The ratio wave have frequency of 3MHz. A radio receiver is moved out from point B along a line BC (perpendicular to AB). The distance from B beyond which the detector does not detect any minima si :

Two identical loudspeakers are placed on a line at distance 4m and 6m from a microphone lying on the line joining them. The output of each speaker at the microphone is 2mW . If the two speakers are connected in series and excited by the same oscillator and they vibrate in phase with each other, the resultant ouput of the microphone will be (frequency of oscillator =660 Hz and speed of sound =330 m//s )

Two equal positive charges are kept at points A and B. The electric potential at the points between A and B (excluding these points ) is studied while moving from A to B. The potential will

The distance between the two identical speakers shown in Fig. 14.3.3 are 4.00m. They are driven by the same osicllator. Initially a listner stays at L at a distance 8.0 m from the centre of the line connecting the two speakers. The listner then walks to the point A where AL=0.4m. The first minium is sound intensity in heard just the listener reaches the point A. Find the frequency of the oscillator. Speed of sound in air is 340 m/s.

Two identical loudspeakers are driven in phase by a common oscillator at 800 Hz and face each other at a distance of 1.25 m . Locate the points along the line joining the two speakers where relative minimum of sound pressure amplitude would be expected. ( Use v = 343 m//s .)
