. What force, in newton, your muscles need to apply
to hold a mass of 5 kg in your hand ? State the
assumption.
​

Answer 1

To hold a mass of 5 kilogram in our hand the force that is applied by the muscles is 50 Newton.

Explanation:

• Here we have assume the acceleration due to gravity of the earth to be kg/m².

• the force which is exerted by the muscles is equal to the force by which the mass is pulled towards the centre of the Earth due to acceleration due to gravity.

• The force of acceleration due to gravity is the mass of the object x the acceleration due to gravity of the earth= 5x10N = 50N
