How Do You Calculate Electric Potential with Opposite Charges?

AI Thread Summary
To calculate the electric potential at a positive charge Q due to both a positive and a negative charge, the potentials from each charge should be summed, not subtracted. Electric potential is a scalar quantity, meaning it does not have direction, so the contributions from each charge can be added directly. The formula for the net potential at point Q is Vnet = V(+) + V(-), where V(+) is the potential from the positive charge and V(-) is from the negative charge. It is important to consider the signs of the charges when calculating their individual potentials. Therefore, the correct approach is to add the potentials together to find the total electric potential at charge Q.

A positive charge Q between two charge , a positive charge and a negative charge .Now I want to find the electric potential at the positive charge Q due to both the charges . The problem I am facing is do I need to minus the
electric potential due to charge positive with the electric potential due to charge negative . I have this problem because the electric potential is a scalar quantity , so if I minus it , it will look like it is a vector quantity .So do I need to minus it or add it together ?

Because Potential is a scalar quantitu , Vnet=V(+) + V(-) , that is summation of potential at that point due to positive charge + potential at that point due to negative charge , while writing the potential terms take the charge +Q or -Q as the case maybe...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
