Explanation:
The given data is as follows.
distance (r) = 1.67 m
= 1 C
It is known that formula for electric force between two charges is as follows.
F =
Hence, putting the given values into the above formula as follows.
=
As it is given that mass of Falcon Heavy rocket is 1421. Therefore, weight of 1 Falcon rocket is as follows.
weight of 1 falcon rocket =
Therefore, number of falcon rockets will be calculated as follows.
No. of falcon rockets =
=
= 2318.9 falcons
Thus, we can conclude that force between the two point charges above is equal to the weight of 2318.9 Falcon Heavy rockets.
Answer:
it yields a derived unit known as Newton, which is the unit of Force.
Explanation:
The formula for force is given by Newton's Second Law, which states that whenever an unbalanced force is applied to a body, it produces an acceleration in the body in the direction of force.
where, F = Force
m = mass
a = acceleration
Now, we substitute the respective S.I units of each quantity in equation:
F = Newton (N)
m = kilogram (kg)
a = acceleration = m/s²
Therefore,
So, it is clear from above expression that:
<u>When kilogram is multiplied by meter per second squared, it yields a derived unit known as Newton, which is the unit of Force.</u>
