Question

by applying a force of one Newton,one can hold body of mass​

Answer 1

Answer:

Explanation:

Newton's third law states that every applied force has an equal but opposite reaction force. In our case, we have a body of mass m being held in air by a force of one Newton. For the body to be held in the air, its weight has to cancel off the applied force, otherwise the body of mass would have a net force resulting in acceleration and movement. In this case we are assuming that the body of mass is stationary. The weight of an object of mass mm is given by

W=mg

where g is the acceleration due to gravity. We want the weight to equal the one Newton applied force. Therefore, the mass of the body is the ratio of the weight W to g.

Given - Approximately, 1 N force is applied.

F = 1 N  

m = ?

F = m x a  

a- acceleration due to gravity    

F = m x g  

1 N = m x 9.8 m/s²

m=1 N / 9.8 m/s²

Thus, m = 0.1020 kg

By applying a force of one Newton, one can hold a body of mass  102 g
