Solution

The correct option is B Melting point
Pure, crystalline solids have a characteristic melting point, the temperature at which the solid melts to become a liquid is called as melting point of the solid.
When solids are heated the kinetic energy of their molecules increases because of that they break the inter molecular bonds present between them and become free from the fixed position.

Q. A particle of mass

5

kg is free to slide on a smooth ring of radius

r = 20

cm fixed in a vertical plane. The particle is attached to one end of a spring whose other end is fixed to the top point O of the ring. Initially the particle is at rest at a point A of the ring such that

∠

= 60^{o}

, C being the centre of the ring. The natural length of the spring is also equal to

r = 20

cm. After the particle is released, it slides down the ring, the contact force between the particle & the ring becomes zero when it reaches the lowest position B. Determine the force constant of the spring.
