Answer:
a) 845 N
b) Towards the center of the earth
Explanation:
Gravity is a force that acts towards the center of the earth. It is the force that pulls an object towards the center of the earth. The whole earth is a large gravitational field.
The gravitational force acting on an object is equal to the mass of that object. The direction of the gravitational force is always towards the center of the earth hence it pulls any object that goes up downwards towards the earth.
