In amplitude modulation, the message signal `V_(m)(t)=10sin(2pixx10^(5)t)` volts and Carrier signal
`V_(C )(t)=20sin(2pixx10^(7)t)` volts The modulated signal now contains the message signal with lower side band and upper side band frequency, therefore the bandwidth of modulated signal is ` alpha` KHz. The value of `alpha` is

200 kHz

50 kHz
