Answer:
Force between the two charges becomes one fourth of the initial force.
Explanation:
The electrostatic force acting between any two charges is given as,

Here,
F = force
k = Coulomb's constant
= magnitude of charge of the first particle
= magnitude of charge of the second particle
= separation between the two charges
From the above relation,
Thus,



Given that
Velocity of missile (v) = 20 m/s ,
Angle of missile (Θ) = 53°
Determine , Vertical component = v sin Θ
= 20 sin 53°
= 15.97 m/s
work done is product of force and displacement of point of application of force
so here we have to check the product of force and displacement both
Now we will put the least to maximum work in the following order
1. -A man exerts strenuous effort in pushing a stationary wall
2. -A flea pushes a speck of dirt 1 cm
3. -A farmer pushes a 2 kg wheelbarrow 20 m
4. -A cannon launches a 3 kg cannonball a distance of 200
5. -A 2000 kg car travels 400 m down a road
6. -Space shuttle Atlantis launches from the ground into near-Earth orbit
