How Is a Charge Deflected by a Fixed Charge in an Electric Field?

AI Thread Summary
A charged particle moving along the x-axis is influenced by a fixed charge located at the origin, resulting in a deflection in the y-direction. The x-component of the particle's velocity remains largely unchanged, while the y-component increases as it approaches the fixed charge. To analyze the deflection, it's essential to determine the vector force acting on the moving charge due to the fixed charge, which varies with position. Participants in the discussion emphasize the need for the original poster to show their work and set up the integral to facilitate assistance. Understanding the integration process is crucial for determining the angle of deflection accurately.

A particle of mass m and charge q moves at high speed along x axis. It it initially near x=-infinity and it ends up near x=+infinity. A second charge Q is fixed at the point x=0, y=-d. As the moving charge passes the stationary charge, its x component of velocity does not change appreciably, but it acquires a small velocity in the y direction. Determine the angle through which the moving charge is deflected.

im quite poor in integration.. any hints, anyone?

We need to see some of your work before we can help you -- PF rules. What is the vector force on the moving charge due to the fixed charge, as a function of position? Show us how you set up the integral that you are having trouble with.
 

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'

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...
