700 N.
Work Step by Step
Ans.
The expression for the weight of a person
w = F_{app} - - - - - - - - - (1)
Where, w = Weight of a person
F_{app} = Applied force that act on bathroom scale
According to problem the person stands with one foot on one bathroom scale and another foot on second bathroom scale so the sum of these two force is applied on the bathroom by the person.
So
F_{app} = F_{1} + F_{2}
Now equation 1 can be written as
w = F_{1} + F_{2}
Here,
F_{1} = Force that applied one foot of the person one bathroom
F_{2} = Force that applied another foot of the person second bathroom
We given F_{1} = 350 N, F_{2} = 350 N
so
w = 350 N + 350 N
w = 700 N
