Question

1. A student says that he had applied a force F = - k✓x on

a particle and the particle moved in simple harmonic

motion. He refuses to tell whether k is a constant or not.

Assume that he has worked only with positive x and no

other force acted on the particle.

(a) As x increases k increases.

(b) As x increases k decreases.

(c) As x increases k remains constant.

(d) The motion cannot be simple harmonic.

2. The time period of a particle in simple harmonic motion

is equal to the time between consecutive appearances of

the particle at a particular point in its motion. This point

is

(a) the mean position (b) an extreme position

(c) between the mean position and the positive extreme

(d) between the mean position and the negative

extreme.
