A particle moves in a plane such that its displacements are the sum of two displacements \(\vec{ r}_1\), and \(\vec{r}_2;\) each of which undergo SHM in opposite phase with respect to the other, but of unequal amplitude. The resultant motion of the particle is:
1. uniform circular motion 
2. elliptical motion
3. linear SHM
4. angular SHM along a circle

A particle is subjected to two SHMs, one along the \(x\text-\)axis and the other along the \(y\text-\)axis:   
\(x=A\sin\omega t\\ y=A\sin(\omega t+\pi)\)
The resulting motion is:
1. Uniform circular motion.
2. Elliptic motion.
3. SHM along a straight line.
4. SHM along a circle.

Two SHMs of the form:
\(x=A+A\text{sin}\omega t\\ y=A-A\text{sin}\omega t\)
are superposed on a particle, along \(x\) and \(y\) directions. The resultant of these motions is:
1. circular motion
2. SHM along \(x\)-axis
3. SHM along \(y\)-axis
4. SHM, but along a direction other than \(x\) or \(y\)-axis

If two SHMs of the same frequency and same amplitude are added but in opposite phase, then, their resultant will be:
1. SHM of same frequency but double amplitude
2. SHM of double frequency but same amplitude
3. SHM of same frequency but smalled amplitude
4. no motion, due to cancellation
