Given below are two statements: Statement I: The escape speed of a body from the surface of Earth depends on the angle at which it is projected relative to the horizontal. Statement II: The escape speed from the surface of the Earth is given by \( V_{\text{min}} = \sqrt{2gR_E} \). In the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.
  2. Both Statement I and Statement II are incorrect.
  3. Statement I is correct but Statement II is incorrect.
  4. Statement I is incorrect but Statement II is correct.

Correct answer · Option 4

Statement I is incorrect but Statement II is correct.

Explanation

Escape velocity is a scalar quantity derived from energy conservation and is independent of the direction/angle of projection. Statement I is incorrect, Statement II is correct.
