Thanks for the idea. I have never really used summation notation, always expanded terms and got my way through. Will try summation from now on.
I realized one thing that ∇.A=A.∇ doesn't hold in this case while it holds with vectors.
yeah that's fine, I just wanted to think if there is any...
While using the ∇ operator, most of the times we can treat it as a vector. I came across a few formulae(basically product rules)..
∇×(A×B)=(B.∇)A-(A.∇)B+A(∇.B)-B(∇.A)
where A and B are vectors
I wanted to know if there is any direct way of deriving it. By direct I mean assuming the basic...
sorry i was a bit late in replying.
i also was not able to understand the same thing.so i thought since Δp is large then p also must be large.so i thought instead of writing Δp as m0v we should write Δp as Δ(m0v/√(1-(v/c)2)) and then find Δv.
but since i have never seen anyone applying...
i tried to apply uncertainty principle to an electron confined in a 3d box of size 1fm.
i got uncertainty in velocity Δv to be of the order 1010 m/sec.so i thought maybe i should have taken relativistic mass instead of rest mass.
but i realized that for calculating relativistic mass we...
