So here's what I attempted with question 1
For r > R the sphere behaves as a point charge
V(r) = Q/4piEor therefore at the surfaces, potential V(R) = Q/4piEor
Va - Vb = Q/4piEor^3 [(rb^2/2) - ra^2/2)]
for rb= R, Vb = Q/4piEoR
Va = Q/4piEoR = Q/8piEor^3 (R^2 - ra^2) + 2Q/8piEoR
that is Va =...
I've been doing some questions and I'm completely stuck on three of them. I tried thinking of how to tackle them but I'm coming up blank.
1. A charge of q is distributed uniformly throughout a spherical volume of radius R. Setting V = 0 at infinity, show the potential at a distance r from the...
I'm looking for structures of ogliosaccarides and homo/heteropolysaccharides but I seem to not be able to come across any. I did searches and checked texts but unfortunately they weren't very helpful. So, can anyone tell me where I find such structures, possibly online? Thanks.
I'm stucked on a practical in which I was supposed to find out how the magnetic force on a current carrying conductor depends on its length, current through it and the magentic field strength. After this I was supposed to plot 3 graphs.
Well, I carried out the expt. using a current balance...
Alright here's a next question which I've attempted nd would like a bit of help with.
I drew a diagram already so here's the question
A cart is conneted by a cord to a hanging block. The cart has a mass m1 = 0.6kg and it's centre of mass is intially at xy coordiantes (-.500m, 0m); the block...
Here's what I did for no.5 even though I can't seem to complete it. I truly don't know how to tackle the other problems though.
So here I go
J = pf - pi = m(vf-vi)
where pf = the momentum just after the ball strike the wall for 10ms
How do i find what vf is?
Jx =m(vfx - vix)...
Well here are 5 questions from my text which I've tried doing but can't seem to twist my ahead around to figure them out. I don't know if it's due to the fact that I'm not applying the relevant concepts. Thanks for any help.
(1). A uniform cord of length 25cm and mass 15g is initally stuck to...
