Question

Lucy lightfoot stands with one foot on one bathroom scale and her other foot on a second bathroom scale. each scale reads 380 n .what is lucy's weight?

Answer 1

Answer: 760 N

Weight is the force acting on the body due to gravity. This weight is shown by weighing scale which measures the normal force acting against the gravitational pull when the person stands on it.

When Lucy stands on the weighing scale, net force due to gravity is $380 N+380 N = 760 N$

Hence, weight of Lucy is 760 N
