Answer:
1.315 m
Explanation:
Assumption: there is no resistance of any type
v= 5.08 m/s
g = 9.81m/s^2
change in kinetic energy = change in gravitational potential energy
mass on both side is same so it cancels out
and also making 'h' alone on one side
h= ((5.08)^2)/(2*9.81)
h =1.3153m
The formula for gravitational force is:
F = G m1 m2 / r^2
where G m1 m2 are constants, therefore:
F r^2 = constant
Part b. Given F1 = 2000 N, r1 = 100 km
Find F2 = ?, r2 = 150 km
(2000 N) * (100 km)^2 = F2 * (150 km)^2
F2 = 888.89 N
Part c. Given F1 = 2000 N, r1 = 100 km
Find F2 = ?, r2 = 50 km
(2000 N) * (100 km)^2 = F2 * (50 km)^2
F2 = 8000 N
Well i think it is false caus ebunch of products these day have metals incorparded in the product

Answer: close together</h2>
The electrical force is a force that is <u>inversely proportional to the square of the distance.</u> This can be proved by Coulomb's Law, which states:
"The electrostatic force between two point charges and is proportional to the product of the charges and inversely proportional to the square of the distance that separates them, and has the direction of the line that joins them"
Mathematically this law is written as:
Where is a proportionality constant.
Therefore, if the charges are close together, this means the distance between them is minimal and the electrical force is increased.
