Q: A particle is released from a height S. At certain height its kinetic energy is three times its potential energy. The height and speed of the particle at that instant are respectively

(a) $\frac{S}{4} , \frac{3 g S}{2}$

(b) $\frac{S}{4} , \frac{\sqrt{3 g S}}{2}$

(c) $\frac{S}{4} , \sqrt{\frac{3 g S}{2}}$

(d) $\frac{S}{3} , \sqrt{\frac{3 g S}{2}}$

Ans: (c)
