In physics course we had a problem ........ the time taken by the charges to collide.. here in this problem the force experienced by the charges is a variable because the distance between them is changing....so as force is a variable this implies it is variable acceleration. but i read a article about variable acceleration by "MILES MATHIS". i urge you to read it once and see if the method used by us to solve the problem is right?? well i would suggest prof.Calvin to go through this and see if it makes a mathematical sense. thank you.
