A girl brings a positively charged rod near a thin neutral stream of water from a tap. She observes that the water stream bends towards her. Instead, if she were to bring a negatively charged rod near to the stream, it will
bend in the same direction
bend in the opposite direction
not bend at all
bend in the opposite direction above and below the rod
What are called conductors and non-conductors ? In which free electrons are more ? Conductor or non-conductor.
Write unit and value of fundamental electric charge.
Write definition of unit Coulomb.
How can you represent experimentally that $(i)$ there are two types of charges and $(ii)$ there is repulsion between two like charges and attraction between two unlike charges ?
The electric charge in uniform motion produces
