From a large distance away, a particle of mass m1 and a positive charge q1 is fired with a speed v in the positive x-direction towards another particle, originally stationary, but free to move, with mass m2 and positive charge q2. Both particles are constrained to move only along the x-axis. A) At the instant of closest approach, both particles will be moving at the same speed. Find this speed.
B) Find the distance of closest approach.
C) After the interaction, the particles will move far apart again. At this time, find the velocity of the following.
1) the particle of mass m1.
2) the particle of mass m2.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
