As the centripetal force acts upon an object moving in a circle at constant speed, the force always acts inward as the velocity of the object is directed tangent to the circle. This would mean that the force is always directed perpendicular to the direction that the object is being displaced.

pseudo actually means "fictitious or false" hence this is a actually a false force. for eg when we are in a car which is at rest and suddenly the car is accelerated then we say that due to inertia of rest we experience a force backward and hence move back.. this is also due to pseudo force that acts on us opposite to the direction of motion of the car.

ANSWER

As we know that escape velocity is that velocity of an object which is require to over come the gravitational field of Earth. For example_ a satellite revolving around the Earth which is launched with its escape velocity . But when it is revolving around the Earth,it should experience Earth's gravitational field which is having high range and should fall down to the Earth's surface but satellite do not so.. Why??
