Question about electric potential at a point

AI Thread Summary
The electric potential at point Z, due to three equal charges that are equidistant from that point, can be calculated using the formula V = kq/r. Since the charges are equal and positioned symmetrically, the total electric potential is the sum of the potentials from each charge. Therefore, the correct approach is to use V = (3kq)/r. This confirms that the contributions from all three charges can be added directly. The solution provided is accurate and valid.

Homework Statement


Three equal charges are equidistant from point Z. What is the electric potential at point Z?

Homework Equations


V = kq/r

The Attempt at a Solution


Because the charges are equal and equidistant from point Z, would I find the electric potential by: V = (3kq)/r ?

Thank you!

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 hanged 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...
