How Far Does a Charged Particle Travel in an Electric Field?

AI Thread Summary
A 1-gram particle with a charge of 1 milliC in a uniform electric field of 10 V/m is analyzed to determine how far it travels in 2 seconds. The initial approach involved using potential energy, but it was suggested to instead calculate the force using F = E*q and then apply F = ma to find the acceleration. After establishing the acceleration, kinematic equations can be used to find the distance traveled. There is a disagreement on the expected distance, with one participant asserting the answer is not 10 meters. The discussion emphasizes the importance of using the correct physics principles to solve the problem.

Homework Statement


A 1-gram particle with a charge of 1 milliC starts from rest in a uniform electric field of magnitude E = 10 V/m. How
far (in m) does the particle travel in 2 seconds?
I know the answere is 10 but I don't know how to find it


Homework Equations


PE/q=-Ex




The Attempt at a Solution


I converted all units but I have PE and change in x left and I am stumped can anyone help

I have PE/.oo1= -10* x

I know the answere is 10m already but I can't figure out how

Don't use PE. Use force F=E*q. Then use F=ma to find the constant acceleration. Now use kinematics to find the distance travelled. I don't think the answer is 10m.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
