Generally we use the left hand rule - (if index finger shows velocity, middle finger shows magnetic field, the thumb points towards force). Recently I also came across a left hand rule for lorentz force- Using your right-hand: point your index finger in the direction of the charge's velocity, v...

5-ethyl-4-methyloctane. Why can't we name this compound as 4-ethyl-5-methyloctane?

Does that mean that the probability of finding the electron on the x-axis is 0 too, as it has no volume like the Z axis?

Let us assume that we have an electron belonging to the px orbital. In that case what would be the probability of finding it on the z axis? Would it be zero? My teacher says so, but I think that because we can't predict the boundary where there is 100% possibility of finding an electron, we...

But what about intial He atom with 2 electrons?

Homework Statement The energy required to ionize a helium atom is 24.6 eV. The energy required to remove both the electrons from He atom would be?The Attempt at a Solution My textbook says- IP1= 24.6 eV IP 2= IP1*Z2 How can they relate the first ionization energy to the second one? The Bohr's...

Homework Statement A fish is 60 cm under water. A bird directly overhead looks at the fish. If the bird is 120 cm above the water level, find the apparent position of the fish as seen by the bird. The question is solved by using the principles of refraction. But, if the bird is directly...

A plane mirror forms a virtual image of a real object placed in front of it and a real image of a virtual object placed in front of it. I can't picture the second case. Please show me a ray diagram showing real image formation by a plane mirror or just explain the case of real image formation by...

Thank you so much for helping me figure out the answer myself!

Oh! I think I got your point. Beams have a net charge as they have only let's say electrons . so they repel due to electrostatic force. Whereas a wire is neutral due to the presence of both electrons and protons. So they is no electrostatic repulsion. Only attraction exists due to moving...

Electrons, which are flowing just the same way as in a beam

Yes each proton carries a net charge.But so does an electron. So if the stream of moving protons is considered charged, applying the similar logic the wire should also be considered charged. Is there any difference in the two cases?

The protons are continuously flowing without any obstruction in the beam as well. So I think the net charge on the beam should be zero too. Please correct me if I'm wrong.

The wires are not charged as electrons are continuously flowing through them. The only difference between the two cases is that in one case electrons are enclosed in a conductor and in the other they aren't. I find this question too confusing. What is the reason?

Question- Two proton beams going in the same direction repel each other whereas two wires carrying current in the same direction attract each other. Why does this happen? Attempt at the solution- Two proton beams should be equal to two currents in the same direction then why are we getting two...
