A toy gun uses a spring of force constant $$k$$. When charged before being triggered in the upward direction, the spring is compressed by a distance $$x$$. If the mass of the shot is $$m$$, on being triggered it will go upto a height of

$$\frac{k x^2}{m g}$$

$$\frac{x^2}{k m g}$$

$$\frac{k x^2}{2 m g}$$

$$\frac{k^2 x^2}{m g}$$

A particle of mass $$m$$ is moving in a horizontal circle of radius $$r$$ under a centripetal force given by $$\left(-k / r^2\right)$$, where $$k$$ is a constant. Then

the total energy of the particle is $$(-k / 2 r)$$

the kinetic energy of the particle is $$(k / r)$$

the potential energy of the particle is $$(k / 2 r)$$

the kinetic energy of the particle is $$(-k / r)$$
