Calculate Point Charge Force on Line Ab | Static Electricity Homework

AI Thread Summary
To calculate the force on point charge C due to charges A and B, the principle of superposition must be applied, as the forces from each charge act independently. The relevant formula is F = k(q1q2)/d², where k is Coulomb's constant, and distances must be correctly identified for each interaction. Charge C is 0.06 m from charge A and 0.14 m from charge B, requiring the calculation of forces from both A and B separately before summing them. The initial confusion about angles is clarified, as the charges are aligned linearly, negating the need for angular calculations. Understanding these concepts is essential for solving the problem accurately.

Homework Statement


Two points charges A(+10. uC) and b(+40.0 uC) are placed .2 m apart forming line ab. Calculate the force experienced by a point charge C(+10.0 uC) placed on line Ab, .06 m from A

Homework Equations


F=kq1q2/d^2

The Attempt at a Solution


First I tried making a diagram of this problem but it didnt really help me in anyway because all I could get out of it was the angle measures. I tried using F=kq1q2/d^2 and plugged in .06 as the distance and 10 uC as the charge but then what would be the point of knowing the two other charges so I think I'm doing something wrong. Can someone tell me what 2 do please

Hi,

What do you mean you found angle measures? If they're all on a straight line, there shouldn't be any angles.

Are you aware of the principle of superposition of forces?

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...
