Answer:
i believe there is something wrong in your question
Explanation:
Both electric force and gravitational force are conservative and obey inverse square law.
The electric force between two charges q and q' separated by a distance r is calculated as-
Here K is the proportionality constant whose value is
The gravitational force between two masses m and m' separated by a distance r is given as -
Here K' is the proportionality constant whose value is G .
G is called gravitational force constant and its value is given
The electric force is a stronger force and gravitational force is a weaker force.
It is obvious that the value of constant for electric force is much larger than the gravitational force constant.
Out of the four options given in the question the the option four is the correct answer i.e D) The electrical force is much larger than the gravitational force because 10^9 is much greater than 10–11.
Answer: 2.5
Explanation:
The mass of bullet = 20kg
The momentum of the bullet = 10kg m/s
The kinetic energy of this bullet in Kj will be calculated as:
= p² / 2m
= 10² /(2 × 20)
= (10 × 10) /(2 × 20)
= 100/40
= 2.5
Therefore, the correct option is C.
