Grade 10Electric Current
a student says that he had applied a force F=-k*sqrt(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 had worked 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
