AI Thread Summary
To find the displacement of a charged particle in a constant electric field, one must first calculate the force acting on the particle using F = qE, where q is the charge and E is the electric field. Next, apply Newton's second law (F = ma) to find the acceleration of the particle. With the acceleration known, use the kinematic equation for displacement, s = ut + 0.5at^2, where u is the initial velocity, a is acceleration, and t is time. The initial velocity is zero since the particle is released from rest. Properly following these steps will yield the correct displacement after the specified time.

I am trying to figure out the displacement from this question:

A particle of charge 12x10^-6 C and mass 3.8x10^-5 kg is released from rest in a region where there is a constant electric field of 480 N/C. What is the displacement of the particle after a time of 1.6x10^-2 s.

I have tried several different ways to approach this but for whatever reason I just can't get it. Please help!

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...
