Question 161 of 223

The escape velocity for a body projected vertically upwards from the surface of earth is 11 km/s11 \mathrm{~km} / \mathrm{s}. If the body is projected at an angle of 45∘45^{\circ} with the vertical, the escape velocity will be

Show answer and solution

Answer: (C) 11 km/s11 \mathrm{~km} / \mathrm{s}

Escape velocity of a body is independent of the angle of projection. Hence, changing the angle of projection is not going to effect the magnitude of escape velocity
