A particle with a charge of 5.0 EXP-9 C moves from point a to point b in thesame direction as the electric field with a magnitude of 3.0 EXP2 N/C . Assumingthat the distance from point a to b is 0.25 m 1. what is the work done on it by the field? 2. what is the magnitude of the force on the charge

I need help solving this problem. I cannot seem to figure it out. Thanks!   There is a uniform electric field, directed toward the right. If an externl force pushes a positive charged particle to the left, what will happen to the electric potential energy of the system?

Don't use chatgpt, please help.

Gravitational acceleration is 9.81m/s2.

so the distance is from -3 to 5 cm which is 8cm or .08m. I did parts a-e and need help for parts f-h. This is what I have so far: a: V1=1000V b: 3.2e^-16 J c. potential energy; no work needed to move particle as it leaves electric field  d. 3.2e^-16 J e. m1<m2<m3<m4, v1>v2>v3>v4 f. distance =.08m -time takes particle 1 hit detector: .98e^-6 sec ---> .08m/.98e^-6 s= 8.16e^4 m/s -time takes particle 2 hit detector: 1.4e^-6 s --> .08m/1.4e^-6 s= 5.71e^4 m/s -time takes particle 3 hit detector: 1.7e^-6 s --> .08m/1.7^-6 s= 4.7053^4 m/s -time takes particle 4 hit detector: 1.96^-6 s --> .08m/1.96^-6 s= 4.082e^4 m/s   I am not sure if i Made any mistakes so please let me know if i DO!

In the diagram, how much work is done by the electric field as a third charge q3 = +3.30 nC is moved from point a to point b? 12.0 cm 12.0 cm 91 92 -8.00- cm 4.00 cm 4.00 cm where q1 = +5.40 nC and q2 = -5.40 nC. HJ

How much work does a uniform electric field of strength, 3,000 N/C, perform on a +2.0-µC point charge that moves a distance of 30 cm in the direction of the electric field?   a. 3.6 mJ   b. 1.8 mJ   c. 3.0 mJ   d. 4.2 mJ   e. 2.4 mJ

Point charges Q1= 1 nC, Q2= -2 nC, Q3= 3 nC and Q4= -4 nC are positioned one at a time and in that order at (0,0,0), (1,0,0), (0,0, -1) and (0,0,1), respectively. Calculate the energy in the system after each charge is positioned.

A proton is held at the positive plate parallel arrangement. The plates are 1.45 cm apart and the proton has a potential energyof 5.45 x 10^-18 Joules.a) What is the electric field strength?b) How much force is needed to hold the proton at the positive plate?c) If the proton is released, what will be its speed just before it strikes the negative plate?
