Explanation:
Given
It is given that the depth is constant and we are only increasing the height of object submerged in the water
thus Force due to Pressure remains same as this force depends upon the depth of object with respect to free surface of Fluid.
Pressure at a depth h with density of fluid is given by
and
Answer:
A. Object A requires twice the force to stop as Object B.
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
<em>Let's assume the following values;</em>
Mass of object B = 10 kg
Mass of object A = 2 * B = 2 * 10 = 20 kg
Acceleration = 5 m/s²
I. To find the force for B;
<em>Force B = 50 Newton</em>
II. To find the force for A;
<em>Force A = 100 Newton</em>
From the calculation, we can deduce that Force A (100 N) is twice or double the value of Force B (50 N).
<em>In conclusion, since object A has twice the mass of object B and both objects are moving at the same speed, object A would require twice the force to stop as Object B.</em>
