A sinusoidal wave $\displaystyle f_1(t)=3 \sin \omega t$ is superposed on another periodic wave $\displaystyle f_2(t)$ which is also oscillating with the same frequency. If the resultant wave is a sinusoidal wave, which is out of phase with $\displaystyle f_1(t)$ by $\displaystyle 53.1^{\circ}$; then the wave $\displaystyle f_2(t)$ would be - [Given $\displaystyle \tan 53.1^{\circ}=1.33$ ]
