If we use r1,r2,r3 then how would the vector operator operator operate on it?Like it didnt in A when we used A1,A2,A3.

No its not..here at least

SOme one help me with the OPD. How is here the OPD=n2(AB + BC) -n1(AD)? I am not confused with the introduction of 'n'..Rather the path length is confusing me..Why is there a negative sign?

Why do we use the coordinates of r in terms of x,y,z?Why don't we express coordinates of A in x,y,z?

How we calculate the duration of depositing a specific amount of charge via a battery on a pure Capacitor when resistance is not present..and we can't use the formulas of RC combinatio?

Is we take two spherical conductors concentric with charge at centre.One of radius r then other of 2r..Will the electric flux through them will be equal? But when we use electric flux= E*A Then won't the electric flux vary as area is different of each sphere?

In transmission lines the the voltage is stepped up to a specified level thereby reducing current to ensure its transmission with minimal power loss. But we know that P=V*I so by increasing the voltage won't Powerloss gets increased?

How can it be a true eq?Electric flux is definitely not zero bw the plates..

In calculating the electric field bw two parallel plate i.e a capacitor I encountered a problem :where to take the Guassian surface..When I consider the Guassian surface.a cube bw the two plates Electric intensity becomes 0..But when I take the Guassian surface with a portion of capictor inside...

I can't do Major in Physics as it will put me economically in an Uncertain Condition.Also the society here(I live in Pakistan) deappreciates such carreers as a Bachelors or Masters in Physics..I must do Engg(To be on safer side and thrive here)..So B.S Mechanical Engg is must..recommend what...

I vow to do something in Particle Physics but some real nast circumstances hinders my desires.So plan to take admission in BS Mechanical Engg and after wards M.S Nuclear Engg..How close might it be to particle Physics where I might end up?If not close enough recommend any other field.

How can an incident photon cause an atom to de excite??

Hey..!Its been a long time since I last posted..Any how I returned.. My question is about mEta stable states in atoms in Lasing Action.Wt actually these states are?And are they justifiable by Bohrs atomic model or Schrödinger Probabilistic orbits?If not then from where these additional states came?

REad about Photon!

That is what I am saying work done should have opposite signs.Taking both works to be positive does this means they hv opposite signs?How?
