A block of mass of 10kg is being pushed on a tabletop downwards by a force of 200N. There is no acceleration in the problem. Calculate the normal force being exerted on the block.

The normal force exerted on the block is 0 Newtons, since it is stated that there is no acceleration, which means that the force exerted can either be not hitting the block. Hence, if we say that the object is accelerated to a certain distance over an interval of time, this means that there is a force exerted on an object. For the given 10kg and 200N, we can set this as an example and find for the acceleration that it will yield.
Formula for force:
F = ma
a = F/m
a = 200N/10kg
a = 20 m/s^2
