Electric Charge

What is Hall effect explain it?

What do you mean by additivity of electric charge?

When two bodies are charged by rubbing them together, they acquire equal and opposite charge.

When the glass rod is rubbed with silk clothes,glass rod becomes positively charged.

Which type of material are usually good conductors of electricity?

Describe Tolman-Stewart experiment.

Explain the idea behind Tolman-Stewart Experiment and the conclusion of the experiment.

Why does distilled water cannot conduct electricity whereas, saline water can conduct electricity?

Write a short note on "liquid conducting current".

Consider a proton present in a region of space. A uniform electric field $5 {\mathrm{NC}}^{-1}$ is applied in the region. Find the acceleration produced in the particle.

Assertion: Copper is a good conductor as its conductivity is more than silicon at room temperature..

Reason: Conductivity of a material depends on the number of free charge carriers present in a material.

What is invariance of electric charge? Explain in brief.
