For a particle performing SHM when displacement is $$x$$, the potential energy and restoring force acting on it is denoted by $$E$$ and $$F$$, respectively. The relation between $$x, E$$ and $$F$$ is

$$\frac{E}{F}+x=0$$

$$\frac{2 E}{F}-x=0$$

$$\frac{2 E}{F}+x=0$$

$$\frac{E}{F}-x=0$$

A person measures a time period of a simple pendulum inside a stationary lift and finds it to be $T$. If the lift starts accelerating upwards with an acceleration $\left(\frac{g}{3}\right)$, the time period of the pendulum will be

$\frac{T}{\sqrt{3}}$

$\sqrt{3} \frac{T}{2}$

$\sqrt{3} T$

$\frac{T}{3}$
