ANSWER

There are two coils A and B separated by some distance. If a current of 2 A flows through A, a magnetic flux of 10 -2 Wb passes through B (no current through B). If no current passes through A and a current of 1 A passes through B, what is the flux through A?

ANSWER

I have read that many aquatic plants found in deep oceans are red in colour, however, I do not understand why. As red is the color which gets the least scattered it should be the only light available to them. Thus reflecting red light would deprive them of any light. Yet they appear to be in red color. Why is this so?

What is invariance property of charge?

Posted by Rohit Singh 8 years ago

CBSE > Class 12 > Physics

2 answers

Amar Kumar 8 years ago

Charge invariance refers to the fixed electrostatic potential of a particle, regardless of speed.
For example, an electron has a specific rest charge. Accelerate that electron, and the charge remains the same (as opposed to the relativistic mass and energy increasing).
Some particle characteristics are relativistically invariant (charge, spin, and magnetic moment).The key is the Lorentz factor.
