Homework Statement Consider a polarised sphere of radius R the polarization is given by P vector = (ar^2 + b) r hat = ( ar+ b/r) r vector Where a and b are constantHomework Equations Find the dipole moment of the sphere The Attempt at a Solution I knew that P (polarized)= delta p / delta...

well yeah I get it thank you thank you so much really appreciate it and thank you for your patient .. Really thank you my problems are solved .. thank you again

if the charge will reside inside each plates .. that's mean the E will be moving from the +ve charge plate to the -ve charge plate so there is no specific place for the charge ! is it like this way ?

will be goes toward the plate with -ve Q .. e) the total will be zero

maybe the charges will be distribute in each plates or maybe it will be going toward the +ve charge .. when the dielectric material placed the E its causing Dielectric polarization Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift...

so u think I've done part B too ? any suggest ?

e) and the potential v will be decreased right ?

a) the charge will be in the inside of each plates so I'm goin to take the first relation which is Sigma = Q/S am I right ? e) the dielectric materials prevent tha charges to flow through the materials so the Q will stay the same and doesn't make any change on the E right ?

I'v doubts bout tha 2nd Q .. C = m-3 D = m2/s Q= m-3/s so L = m .. is that right ! while D grows by 10,000 " assume the remaining is constant " L = 100 is that tha better way to explain tha part B in Q 2 ?

please guys any hint for the 2nd Q ??

well okay I'll try .. but please I need ur correction the 1st one bout simply eq. for capacitor .. so az I learned the first one its bout ( charge density ( sigma ) = charge (q) / area ( S ) ) and cus its bout one plate I think I've to dividin the equ. by 2 ! so it 'll be like Sigma = q/2*S...

Hey all I'd like to help me.. thnx in advance here z tha Q's : 1) Two plane parallel conducting plates each have area S and are separated by a distance b. One carries a charge +Q ; the other carries a charge -Q. Neglect edge effects a) What is the charge per unit area on each plate ? where...
