For every action, there is an equal and opposite reaction (Newton's third law of motion)..

The object accelerates downwards in response to the attractive force of gravity.
The force exerted by the sun on any object depends on the mass of that object so there is no simple answer. The sun's force of a planet like Jupiter will be several orders of magnitude greater than the force exerted on an electron, for example.
1.46 Pascals is exerted on the board.
That is called pressure. For example, the SI unit for pressure is the Pascal, which is equal to newtons / square meters.
it would remain motionless.
5 Million Newtons was the pressure exerted by Saturn v rocket
