Electric field and point charges

AI Thread Summary
To solve for the charge on q2 using the equation E = (k)(q)/r^2, first calculate the distance between q2 and point p. Once the distance is determined, rearrange the equation to isolate q. This will allow for the calculation of q2 based on the provided variables. Understanding the relationship between the electric field and the charges is crucial for solving the problem. The key steps involve identifying distances and rearranging the formula appropriately.

Homework Equations


E = (k)(q)/r^2


The Attempt at a Solution


I know that for this question I am supposed to use the equation "E = (k)(q)/r^2" but the question has me kinda confused. Could someone please tell me what my first step should be in finding the charge on q2?

Well you have been given all of the variables except for q2 firstly calculate the distance between q2 and p then rearrange the equation to make q the subject
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
