An object placed on the ground is in stable equilibrium. If the object is given a slight push, then initially the position of centre of gravity

Options

  1. Amoves nearer to ground
  2. Brises higher above the ground
  3. Cremains as such
  4. Dmay remain at same level

Correct answer

B. rises higher above the ground

Step-by-step solution

In stable equilibrium, the centre of gravity of object, lies at minimum height from ground. As the object is given a slight push, its centre of gravity rises because it comes in unstable equilibrium.
