The new force becomes One Ninth (1/9) of the original force.
The force between two point charges (let's say 
) is given by the following formula:
Force 
divided by ( 
squared)
Here r is the distance.
If we multiply r by three then after squaring it will become 
squared.
Let's rewrite the formula and call it new Force:
New Force 
divided by 
squared )
Now just separate the 9 :
New Force 
divided by 
Squared ))
New Force 
(Force)
So turns out that the new force becomes One Ninth (1/9) of the original force.
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to define force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Answer:
1626.4 N
Explanation:
Given that a 82 kg man, at rest, drops from a diving board 3.0 m above the surface of the water and comes to rest 0.55 s after reaching the water. What force does the water exert on him?
The parameters to be considered are:
Distance S = 3m
Time t = 0.55s
Since the man started from rest, initial velocity u = 0
Using second equation of motion
S = Ut + 1/2at^2
3 = 1/2 × a × 0.55^2
3 = 1/2 × a × 0.3025
a = 3/ 0.15125
a = 19.83 m/s^2
Force = mass × acceleration
Force = 82 × 19.83
Force = 1626.4 N
Therefore, the force that water exerted on him is 1626.4 N

Answer:
Hypotheses must be testable, and once tested, they can be supported by evidence. If a statement is made that cannot be tested and disproved, then it is not a hypothesis.
