How can players reduce reaction time during a chase?
Random signal drills enhance reaction time by conditioning players to respond quickly to unexpected cues. In Kho-Kho, where every second counts, immediate reactions to signals improve chasers’ ability to tag defenders and help defenders dodge effectively. These drills sharpen reflexes and boost overRead more
Random signal drills enhance reaction time by conditioning players to respond quickly to unexpected cues. In Kho-Kho, where every second counts, immediate reactions to signals improve chasers’ ability to tag defenders and help defenders dodge effectively. These drills sharpen reflexes and boost overall game performance through faster decision-making, helping players stay competitive during intense matches.

What is the correct body posture during a pole dive?
A proper pole dive requires maintaining a low and slightly leaning posture. As the player approaches the pole, they should keep their knees bent and body weight forward. This stance ensures balance, reduces injury risks, and maximizes reach during the dive. Effective pole dives require precise bodyRead more
A proper pole dive requires maintaining a low and slightly leaning posture. As the player approaches the pole, they should keep their knees bent and body weight forward. This stance ensures balance, reduces injury risks, and maximizes reach during the dive. Effective pole dives require precise body positioning, helping chasers tag defenders quickly and efficiently near poles.

A particle of mass 10 g is kept on the surface of a uniform sphere of mass 100 kg and radius 10 cm. Find the work to be done against the gravitational force between them to take the particle far away from the sphere. You may takr G = 6.67 x 10⁻¹¹ Nm² kg⁻²
To calculate the work required to move a particle away from a sphere, we consider the gravitational potential energy between the two. The particle has a mass of 10 g (0.01 kg), and the sphere has a mass of 100 kg with a radius of 10 cm (0.1 m). The work done is equivalent to the energy needed to oveRead more
To calculate the work required to move a particle away from a sphere, we consider the gravitational potential energy between the two. The particle has a mass of 10 g (0.01 kg), and the sphere has a mass of 100 kg with a radius of 10 cm (0.1 m). The work done is equivalent to the energy needed to overcome the gravitational attraction and take the particle far away, where gravitational potential energy becomes zero.
Gravitational potential energy is determined by the masses involved, the gravitational constant G = 6.67 x 10⁻¹¹ Nm² kg⁻², and the distance between the centers of mass. At the sphere’s surface, this distance is equal to the sphere’s radius (0.1 m).
Substituting the given values into the formula for gravitational potential energy, the calculation shows that the work required to take the particle far away is 6.67 x 10⁻¹⁰ J. This value represents the energy needed to overcome the gravitational pull between the sphere and the particle.
Hence, the work to be done is 6.67 x 10⁻¹⁰ J, reflecting the small but measurable gravitational interaction between the particle and the sphere due to their masses and proximity.
