Solving a Suspended Ball in an Electric Field

AI Thread Summary
To solve for the electric field strength of a suspended ball with a mass of 0.30 kg and a charge of 500 x 10^-4 C, the equation E = F/Q is applied. The user initially struggled with the force triangle diagram but received clarification on the direction of the tension force. After correcting the triangle, they successfully calculated the electric field strength as 1.25 x 10^3 N/C directed to the left. The discussion highlights the importance of accurately representing forces in equilibrium situations. Overall, the interaction led to a clearer understanding of the problem and its solution.

Homework Statement



a 030 kg ball is suspended in a uniform electric field as shown. If the charge on the ball is 500 x10^-4 C, what is the electric field strength?

Homework Equations



E= F/Q

The Attempt at a Solution



I did this by using the triangle method. draw the forces with a triangle(look at the attachment).
My question is did i draw the triangle right? Does the direction of the Electric field affect my answer?

My question is did i draw the triangle right?
Since the ball is in equilibrium, the forces on it must add to zero.
Look at the direction of the tension force in your triangle.
 
oh my, thank you so much ap123!

I just got the tension force backwards, now it makes much more sense! thank you !
 
Have you worked out the value for the electric field?
 
yes i got 1.25 x10^3 N/C to the left
 
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...
