How Does Electric Potential Affect Proton Movement?

AI Thread Summary
The discussion centers on the relationship between electric potential and proton movement, specifically regarding a proton placed on a metal plate at 1.8 Volts. The electric potential energy of the proton can be calculated using the formula that relates voltage to potential energy per unit charge. After the proton moves away from the plate, its speed can be determined by considering the conversion of electric potential energy to kinetic energy. Participants are encouraged to apply relevant equations to solve for both the electric potential energy in Joules and the final speed of the proton in meters per second. Understanding these concepts is crucial for solving problems related to electric potential and particle dynamics.

Homework Statement


Suppose that a metal plate is held at an electric potential of 1.8 Volts. A proton is placed on the plate where it is repelled by the plate. What is the electric potential energy of the proton measured in Joules? __ x 10-19 Joules
After the proton has moved away from the plate, and all the electric potential energy is gone, how fast will the proton be moving? __meters/second

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...
