The electrical force between two charges is given by
![F=k \frac{q_1 q_2}{r^2}](https://tex.z-dn.net/?f=F%3Dk%20%5Cfrac%7Bq_1%20q_2%7D%7Br%5E2%7D%20)
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the two charges
We see that the magnitude of the force is inversely proportional to the square of the distance. Therefore, if the distance is increased to 3 times the original distance:
![r'=3 r](https://tex.z-dn.net/?f=r%27%3D3%20r)
the magnitude of the force will change as
![F' \sim \frac{1}{(3r)^2}= \frac{1}{9 r^2} = \frac{1}{9} F](https://tex.z-dn.net/?f=F%27%20%5Csim%20%20%5Cfrac%7B1%7D%7B%283r%29%5E2%7D%3D%20%5Cfrac%7B1%7D%7B9%20r%5E2%7D%20%3D%20%20%5Cfrac%7B1%7D%7B9%7D%20F%20%20)
So, the correct answer is <span>
it will decrease to one-ninth the original force.</span>
An organism that lives in or on an organism of another species (its host) and benefits by deriving nutrients at the other's expense.
Answer:
a) amount of kinetic energy converted to internal energy = 2.5 x 10 raised to power 7 Joule
b) Kinetic energy gained by the earth = 2.1 x 10-16J
c) All the kinetic energy is converted to internal energy and the energy is further converted to thermal energy hence the reason for the hotness at around where the meteorite strikes.
