Y= 7+(3-2x)
y =7+3-2x
y =10-2x
y-10= -2x
(y-10)/ - 2 =x
X=(y-10)/ - 2

The change in the kinetic energy of the system from when it is released to the instant it hits the ground is most nearly; (My + Mx)gH
We are told that the two objects X and Y are held together by a light string.
Their masses are;
Mass of Object X = Mx
Mass of objetc Y = My
Since the two objects are released from rest, it means we need to find potential energy and the formula for potential energy is;
P.E = mgh
Now, since both objects are released from rest and since My is larger than Mx, it means that potential energy is now;
ΔP.E = (My + Mx)gH
Now, according to conservation of energy,
Change in kinetic energy = Change in potential energy.
Thus;
Change in kinetic energy = (My + Mx)gH

Answer:
Step 1
The expression for the electric force between 2 charges is given as
F=k q1q2/r2
Here
F is the electric force
k is the coulombs constant
q1 is the charge on 1st particle
q2 is the charge on second particle
r is the distance the charges
Step 2
From the above expression we can clearly see that the force has the inverse relation with the square of distance between the charges. So if the distance between the charges increases, force will decrease.
Therefore, when the distance between the object increases, the magnitude of the force decreases.
