(b) : The centripetal and centrifugal forces disappear, the satellite has the tangential velocity and it will move in a straight line Compare Lorentzian force on charges in the cyclotron.

(d) will depend on direction of projection. EXPLANATION:  Its minimum escape speed will be vₑ when projected vertically upward, but if projected otherwise the speed will be greater. So the escape speed will depend on...
