# The modulation frequency of an AM radio station is 250 kHz, which is 10% of the carrier wave. If another AM station approaches you for license what broadcast frequency will you allot? (a) 2750 kHz (b) 2000 kHz (c) 2250 kHz (d) 2900 kHz

## Question ID - 50257 :- The modulation frequency of an AM radio station is 250 kHz, which is 10% of the carrier wave. If another AM station approaches you for license what broadcast frequency will you allot? (a) 2750 kHz (b) 2000 kHz (c) 2250 kHz (d) 2900 kHz

3537

==2500 kHz

∴Range of signal=2250 Hz to 2750 Hz

Now check all options:

for 2000 KHZ =200 Hz

∴Range =1800 kHz to 2200 kHz

Next Question :
 A hope and a solid cylinder of same mass and radius are made of a permanent magnetic material with their magnetic moment parallel to their respective axes. But the magnetic moment of hoop is twice of solid cylinder. They are placed in a uniform magnetic field in such a manner that their magnetic moments make a small angle with the field. If the oscillation periods if hoop and cylinder are Th and Tc respectively, then: (a) Th=0.5 Tc (b) Th=2 Tc (c) Th=1.5 Tc (d) Th=Tc
