in an experiment in space, one proton is held fixed and another proton is released from rest a distance of 2.50 mm away.

a. what is the initial acceleration of the proton after it is released?

b. sketch qualitatively the acceleration-time & velocity-time graphs of the released proton's motion.

well, the force between them is q1q2/r^2
so, calculate the force between them by putting the values of charge of proton
divide the value of force by proton's mass
u will get the answer

ummm does proton 2 have a reacting force against proton 1? just wondering because i'm quite new to this..sorry for sounding noobs :s

anonymous · Answer

well, there will be electrostatic force between them

anonymous · Answer

tnx, bro! n_n

anonymous · Answer

welcome and np :)

anonymous · Answer

by the way, are the graphs of the released proton constant?

anonymous · Answer

graphs of released protons? means?

anonymous · Answer

pls refer letter b. of my problem.

anonymous · Answer

no, no-- those will not be constant

anonymous · Answer

as the distance will change, the force as well as acceleration and velocity will decrease too :)

anonymous · Answer

\m/ tnx again! that would be all!

anonymous · Answer

sorry, bro! as the distance will increase, the acceleration will decrease, but it will be still positive. so, velocity will increase. :)
