1. A motion can be oscillatory but not simple harmonic.

Correct Answer is : TRUE

2. A particle executes simple harmonic motion between x = -A and x = +A. The time taken for it to go from 0 to A/2 is T1 and to go from A/2 to A is T2. Then

Correct Answer is : T1 < T2

3. A particle free to move along the x-axis has potential energy given by U(x) = k [1-exp -x2] for -∞≤x≤+∞, where k is a positive constant of appropriate dimensions. Then

Correct Answer is : The motion is simple harmonic for small displacement from x=0

4. A simple pendulum has a time period T1, when on the earth’s surface; and T2, when taken to a height R above the earth’s surface (R is the radius of the earth). The value of T2/T1 is

Correct Answer is : 1

5. A coin is placed on a horizontal platform, which undergoes vertical simple harmonic motion of angular frequency ω. The amplitude of oscillation is gradually increased. The coin will leave contact with the platform for the first time

Correct Answer is : For an amplitude of g/ω2
