Expert Answer:

It's 11 km/s. Escape velocity doesn't depend upon angle of projection.

The intensity of the gravitational field will be zero, at the point where the gravitational force will be zero. Let the distance is x from small body.

G(100)(10000)/x2 =  G(100)(10000)/(1-x)2

x2 =  (1-x)2

x = 1/2 m.

(iii) More than 90°
