ok thanks for all the help

So I will take this ( D∫∇E)=KE and solve for v by putting in 1/2mv^2 for KE how did you go from (D (dot) gradient)E to D(gradient E)

sorry spent all day studying for another exam and guess i started to mix up variable ha... so basically i sould get Dx(∇Ex)= Fx is D a constant at this point? then by using the eqs W=∫F and W=\DeltaKE we get \DeltaKE = ∫F = initial KE then using what i made the mistake of doing last night...

that makes since... so what would i do at this point... Fx = D * grad Ex and plug 1/2 m v2 for Ex then solve for V

sorry its supposed to be 0 < θ < π/2 i must have made a mistake typing it

the formula i was given today by my instructor was F = (p (dot product) ∇)E He also said that I needed to find the potential first... now how do you take the reverse divergence as shown above for the p(dot)∇ and how would i find the potential of this by solving for E and pluging that E into...
