## jeroroXno2drugs 4 years ago 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. /*badly needed ASAP*/ ty! @Physics

1. Arnab09

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

3. Arnab09

well, there will be electrostatic force between them

4. jeroroXno2drugs

tnx, bro! n_n

5. Arnab09

welcome and np :)

6. jeroroXno2drugs

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

7. Arnab09

graphs of released protons? means?

8. jeroroXno2drugs

pls refer letter b. of my problem.

9. Arnab09

no, no-- those will not be constant

10. Arnab09

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

11. jeroroXno2drugs

\m/ tnx again! that would be all!

12. Arnab09

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