Angle of deflection of electron

AI Thread Summary
The discussion focuses on calculating the angle of deflection of an electron between two charged parallel plates. An electron is projected horizontally with a velocity of 6.0 x 10^6 m/s and experiences a constant electric force of 3.4 x 10^-17 N. Participants highlight that there is no horizontal force acting on the electron, only a vertical force due to the electric field. To find the angle of deflection, the time the electron spends between the plates must be calculated first. The conversation emphasizes understanding the forces acting on the electron to solve the problem accurately.

Homework Statement


2 parallel plates of length 4.0 cm are arranged horizontally in a vacuum. The upper plate is positively charged and the lower plate is negatively charged. An electron is projected horizontally with an initial velocity of 6.0 x 106 ms-1 and experiences a constant electric force of 3.4 x 10-17 N whilst between the plates. Negating any gravitational effects, find the angle the electron makes with the horizontal on leaving the plates.

Homework Equations


Not that I know of

The Attempt at a Solution


The electron experiences an attractive force of 3.4 x 10-17 N towards the positively charged plate. I don't know the horizontal component of the force acting on the electron so I can't calculate the resultant force.

What makes you think there is a horizontal component or force?
 
you know the horizontal VELOCITY..can you calculate the time that the electron is between the plates?
 

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...
