Solving a Two-Charge System: Find Acceleration & Velocity

AI Thread Summary
To solve the problem of two charges, one fixed and one free to move, the first step is to derive an equation for the acceleration of the moving charge (q2) based on the separation distance (d). The second part requires formulating an equation for the velocity of q2 as a function of time (t). Forum participants emphasize the need to show initial work or attempts at solving the problem to receive assistance, as per community guidelines. The discussion highlights the importance of understanding the forces acting on q2 due to the electric field created by q1. Engaging with the community effectively will enhance the problem-solving process.

Hey I need some help figuring out this problem
Diagram is attached below
Thanks

Two charges are arranged as shown below. Particle q1 is fixed in it's position but q2 is free to move. Assume the two particles start at rest with separation near zero. The mass of q2 is m.



a. Create an equation that will give the acceleration of q2 in terms of the seperation, d.

b. Create an equation that will give the velocity of q2 in terms of time, t.

I'm afraid I won't be able to help you until your attachment is approved by one of our mentors. However, note that also you must show some work before we can help you with homework problems; forum rules, I'm afraid.

So, what have you tried thus far?
 

Thread 'Struggling to understand the concept of this 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...

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}...
