Electrostatic Potential of a Charged Metallic Shell

AI Thread Summary
The discussion revolves around calculating the charge on a charged metallic spherical shell given its potential at a specific distance. The potential formula V = kQ/r is applied, leading to a charge calculation of Q = 1.7E-8 Coulombs. There is a clarification that the radius of the shell will be relevant for the next part of the problem. The units used for charge are confirmed to be in Coulombs. The calculation is deemed correct for the given parameters.

Homework Statement



Given a charged metallic spherical shell of radius a=2.75cm, with a potential of 2.5kV a distance of r=6.0cm from the center of the shell, what is the charge on the shell? Calculate the potential on the surface of the shell.

Homework Equations



V=kQ/r

The Attempt at a Solution



I am assuming that I should just insert values into the equation, so...

2500V = (8.99E9)(Q)/(.060m)
Q = 1.7E-8

Is this calculation correct? I am not sure if the radius of the shell needs to be considered. Also, am I using the right units and are the units of Q Coulombs?

Calculation is correct! Radius will be considered in the second part of the question.:smile:

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...
