${V}_{{m}}({t})=10 \sin \left(2 \pi \times 10^{5} {t}\right)$ $volts$ and
Carrier signal
${V}_{{c}}({t})=20 \sin \left(2 \pi \times 10^{7} {t}\right)$ $volts$
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 :
