The speed at which a proton strikes the positive plate (uniform electric field).

AI Thread Summary
The discussion revolves around calculating the speed of a proton striking a positive plate in a uniform electric field. The original poster struggled with the problem, attempting various equations related to electric fields and forces but found no success. After receiving guidance, they recalled the equation F = qE and decided to apply it to determine the force acting on the proton. Ultimately, they reported success in solving the problem after further attempts. The conversation highlights the collaborative nature of problem-solving in physics.

Homework Equations



No equations are given. Assumed use of standard equations for electric field and force involving electric field.

The Attempt at a Solution


I tried using a few equations (E = F/q0), (F = mv^2), (E=(1/(4piEp0))(q/r^2)), and solving, but no luck. Could someone please give me guidance?

If you can determine the force F acting on the charge, and this force acts on the proton over a distance of 7 cm, how much work is done?
 
Alright so I just remembered the simple equation F = qE so now I'm going to attempt what you said. Physics is not my strength however, so I will probably be back.

No worries, we'll be here!
 
Thank you for your tip. I was able to solve it!
 
Excellent.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Egg Drop Challenge! Need ideas for winning designs'

I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
