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

Given below are two statements: 
Statement I: If the acceleration of a particle is directed towards a fixed point, and proportional to the distance from that point – the motion is SHM.
Statement II: During SHM, the kinetic energy of the particle oscillates at twice the frequency of the SHM.
 
1. Statement I is incorrect and Statement II is correct.
2. Both Statement I and Statement II are correct.
3. Both Statement I and Statement II are incorrect.
4. Statement I is correct and Statement II is incorrect.

Two identical simple pendulums are compared, one \((A)\) located on the surface of the earth and the other \((B)\) – at a height \((h)\) above the earth's surface:    \(h=\dfrac{R}{1000}.\)
Their time periods are related as:
1. \(T_A\Big(1+\dfrac{1}{1000}\Big)=T_B\)
2. \(T_B\Big(1+\dfrac{1}{1000}\Big)=T_A\)
3. \(T_A\Big(1+\dfrac{1}{2000}\Big)=T_B\)
4. \(T_B\Big(1+\dfrac{1}{2000}\Big)=T_A\)

A block of mass \(m\) is pushed towards a spring of spring constant \(k,\) with a speed \(u.\) It is very close to the spring, initially. After a time \(t,\) the block rebounds and returns to its initial position. If \(u\) is increased, then:
      
1. \(t\) increases.
2. \(t\) decreases.
3. \(t\) remains unchanged.
4. the effect on \(t\) cannot be determined due to insufficient information.

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 light rod \(AB\) is hinged at \(A\) so that it is free to rotate about \(A.\) It is initially horizontal with a small block of mass \(m\) attached at \(B,\) and a spring (constant - \(k\)) holding it vertically up at its mid-point. The time period of vertical oscillations of the system is: 
              
1. \(2 \pi \sqrt{\dfrac{m}{k}} \) 2. \(\pi \sqrt{\dfrac{m}{k}} \)
3. \(4\pi \sqrt{\dfrac{m}{k}}\) 4. \(\dfrac{\pi}{2} \sqrt{\dfrac{m}{k}}\)
