Calculate the force of an 8kg object pushing up from the table

The correct answer to the question is: 78.4 N.

CALCULATION:

As per the question, the mass of the object is given as m = 8 Kg.

We are asked to calculate the force of 8 Kg object pushing up from the table.

The force pushing up from the table is nothing else than the normal reaction.

The normal reaction of the object is equal to the weight of the object as the object is simply resting on the table.

Hence, normal reaction = Weight

                                               = mg

                                               = 8 × 9.8 N.

                                                = 78.4 N.

Here, g is known as acceleration due to gravity.

Hence, the force of the object pushing up from the table is 78.4 N.
