Which of the following changes would increase the force between two

Physics
1 answer:
Tomtit [17]2 years ago
8 0

The answer is A. Decreasing the distance between the particles by a factor of 3.

The Universal Law of Gravitation is :

F = Gm₁m₂ / r² (where 'r' is the distance between them)

Since force is inversely proportional to the square of the distance between them, distance has to be decreased by a factor of 3 to increase the force to 9 times the original force.

PLEASE HELPPPPPPP!!!!!!!!!!
natka813 [3]

Answer:

F' = 800 N

Explanation:

The electrical force between charges is 400 N.

The electrical force between two charges is given by :

F=k\dfrac{q_1q_2}{r^2}

If q₁' = 2q₁, new force becomes,

F'=k\dfrac{q_1'q_2'}{r^2}\\\\F'=k\dfrac{2q_1\times q_2}{r^2}\\\\F'=2\times F\\\\F'=2\times 400\\\\F'=800\ N

So, the new force becomes 800 N.

A physics student in a hot air balloon ascends vertically at constant speed. Consider the following four forces that arise in th
Sauron [17]

Answer:

F2 and F3 forms action-reaction pair

Explanation:

In accordance to Newton's third law of motion, action-reaction pairs are formed.

The law is based on the fact that for every action there exist a force that acts opposite and equal to the action force resulting in action reaction pair as they act on different object leading to the motion.

Here, the hot air balloon is in vertically upward motion at constant speed, the speed remains same resulting in no acceleration and also the weight of the student exerts a force opposed by the force exerted by the balloon
