Explanation:
Given that,
Mass of ball 1,
Initial speed of ball 1,
Mass of ball 2,
Initial speed of ball 2, (at rest)
After the collision,
Final speed of ball 2,
Let is the final speed of ball 1.
Initial momentum of the system is :
Final momentum of the system is :
According the law of conservation of linear momentum :
initial momentum = final momentum
So, the final velocity of ball 1 is (-2.616)m/s.
Explanation:
It is given that, an electron and a proton are separated by a distance of 1.0 m i.e d = 1 m . At this position, F is the force between them
...............(1)
We need to find effect on force between them if the electron moves 0.5 m away from the proton. Let the force is F'.
...............(2)
On dividing equation (1) and (2) we get :
F' = 4 F
So, the distance between the electron and the proton is 0.5 m, the new force will be 4 times of previous force.
