By applying a force of 1N, approx. what mass of body can a person hold?
Here the person is holding the weight against the pull of gravity. The force exerted (F) would thus be
F = mg
where m is the mass and g is the acceleration due to gravity.
so, m = F/g
given: F = 1 N
and we know g = 10 m/s2
thus m = 1/10 = 0.1 kg
which is the required answer.
