Question

Lucy lightfoot stands with one foot on one bathroom scale and her other foot on a second bathroom scale. Each scale reads 350 N. what's Lucy's weight?

Steps please..

Answer 1

Here each scale reads `350N`.
So the weight of the body has been equally divided in two scales.

Hence Lucy's body weight will be

`=2*350N=700N=70kgf`

Answer 2

As both the scales are giving same reading that means,her body weight got equally distributed in between her two legs.

So,her total weight is `(350+350) N = 700N`

So,she weighs about `700/10 Kg = 70 Kg`
