Six marbles are lined Up in a straight groove made on a horizontal frictionless surface as shown below. Two similar marbles in contact, with a common velocity v collide with a row of 6 marbles from left. Which of the following is observed?

The acceleration due to gravity at a height h above the earths surface is $ 9m{{s}^{-2}}. $ If $ g=10\text{ }m{{s}^{-2}} $ on the earths surface, its value at a point at an equal distance h below the surface of the earth is

The focal length of a spherical mirror made of steel is $150 \,cm$. If the temperature of the mirror increases by $200\, K$, its focal length become (coefficient of linear expansion of steel $\alpha=12 \times 10^{-6 \circ} C ^{-1} .$ )

The hybridisation of atom $'X'$ with atomic number $27$ in $\left[X F _{6}\right]^{3-}$ is

The kinetic energy K of a particle of mass m moving along a circle of radius R depends on distance covered s as K= as2. Then the acceleration of particle is given by

The kinetic energy of a body rotating at 300 revolutions per minute is 62.8 J. Its angular momentum $ (\text{in kg}\,{{m}^{2}}{{s}^{-1}}) $ is approximately:

Two particles A and B initially at rest move towards each other under a mutual force of attraction. At the instant when the velocity of A is v and that of B is 2v. The velocity of centre of mass of the system is
