According to a scientists, he applied a force `F = -cx^(1//3)` on a particle and the particle is performing SHM. No other force acted on the particle. He refuses to tell whether `c` is a constant or not. Assume that he had worked only with positive `x` then :

Options

A. as `x` increases `c` also increases
B. as `x` increases `c` also decreases
C. as `x` increases `c` remain constant
D. the motion cannot be SHM

Answer

A
