capacitor problem ..help please! Homework Statement Four metallic plates are placed as shown (attachment). Plate 2 is given charge Q whereas all other plates are uncharged initially .Plate 1 and 4 are earthed.The area(A) of each plate is same . q1) The charge appearing on the right...

in any junction diode or transistor...i don't understand the difference between minority charge carriers, majority charge carriers and the immobile charges that you see in the depletion region ..please explain??

oh ..thank you!...this is an awesome site for doubt clarification!

oh ...okkkk...so i do this for left half of the rope ... in x direction ... its ... t1cos@=t2..(1 then t1sin@=mg/2...(2 so i divide 1/2 and cot@=2*t2/mg.. so t2=(mg cot@)/2...! right??!

ok ...i take the tension to be t1 at point A...and t2 at bottom most point then t1sin@=mg...then how to proceed??

mechanics question..please help! Homework Statement a thread hangs between 2 hinges A and B. gravity is acting. The angle(acute) made by tangent to rope at point A and the line AB is @. find the tension at the lower most point..i.e the mid point of the rope? Homework Equations...
