Potential Energy and the Electric Potential Difference

AI Thread Summary
A particle with a charge of +1.5 microcoulombs moves 0.20 m under a constant electric force, resulting in an electric potential energy difference of +9.0 x 10^-4 J between points A and B. To find the magnitude and direction of the electric force acting on the particle, one can use the relationship between electric potential energy and force. The electric field experienced by the particle can also be determined from the force and charge. The discussion emphasizes the connection between the electric force exerted by the electric field and the changes in electric potential energy. Understanding these relationships is crucial for solving the problem effectively.

I'm back again this week with a problem:

A particle has a charge of +1.5 Micro Coulombs and moves from point A to point B, a distance of .20 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = +9.0x10-4 J. (a) Find the magnitude and direction of the electric force that acts on the particle. (b) Find the magnitude and direction of the electric field that the particle experiences.

What have you done regarding this? How does the force exerted by the E-field relate to its electric potential energy?
 
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 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...
