# The escape velocity from earth is 11.2 km per sec. If a body is to be projected in a direction making an angle 45° to the vertical, then the escape velocity is Option 1) 11.2 × 2 km/sec Option 2) 11.2 km/sec Option 3)   Km/sec Option 4)

As we learnt in

Escape velocity -

Minimum velocity which is required to escape the body from earth's gravitational pull

- wherein

It is independent of the mass and direction of projection of body.

Escape velocity is independent of direction of projection. Hence it will remain same for all direction.

This is incorrect option

Option 2)

11.2 km/sec

This is correct option

Option 3)

Km/sec

This is incorrect option

Option 4)

This is incorrect option
