Answer:
The final velocity of apple and arrow after the collision is 2 m/s.
Explanation:
Given that,
Mass of an arrow, m = 0.5 kg
Initial velocity of the arrow, v = 10 m/s
Mass of an apple, m' = 2 kg
Initial velocity of the arrow, v' = 0 (at rest)
We need to find the final velocity of apple and arrow after the collision. After the collision, the arrow and the apple are stuck together. It is a case of inelastic collision. Let V is the final velocity of apple and arrow after the collision. Using the conservation of linear momentum as :
So, the final velocity of apple and arrow after the collision is 2 m/s.
Solution
In this question we have given
Charge,
Charge,
Charge,
Distance between Charge and ,d=43cm=.43m
Let the distance between charge and , is x
Therefore,distance between charge and , will be=(.43-x)
We know By Couloms law, Force on Charge due to charge which are seperated by distance d is given by following equation
............(1)
Here, K=
Therefore,
Force on Charge due to charge
..(2)
Similarly,
Force on Charge due to charge
..(2)
In equilibrium condition,
on solving we get
x=.277m
0r x=28cm
The distance between charge and , is 28cm

Blue would bend the most, since it has a greater refractive index. It has more energy and a shorter wavelength, so it slows.
