The right answer is 280 N.
When a woman stands with two feet on a scale, the scale reads 280 N and when she lifts one foot, the scale also reads 280 N because the weight of the other leg also comes on the one leg.
First, the whole weight of the body depends on two feet but when the second feet is lifted, the weight of the whole body including the lifted feet comes on the single feed so we can conclude that the right answer is 280 N

Answer:
The Acceleration will increase
Explanation:
Newton's Second Law of motion: It states that the rate of change of momentum is directly proportional to the applied force and takes places along the direction of the force.
It can be expressed mathematically as,
F ∝ m(v-u)/t
Where (v-u)/t = a
F = kma.
F = force, m = mass of the body, a = acceleration, k = constant of proportionality which tend to unity for a unit force, a unit mass, and a unit acceleration.
Therefore,
F = ma.
From the equation above,
If the net force acting on a body increase, while the mass of the body remains constant, the acceleration will also increase.
