Electric Charge...

An electric filament bulb can be worked from

The safety fuse should have

Opening up of strips of an electroscope is an indication of:

A charge of $$1 \mu C$$ is divided into two parts such that their charges are in the ratio of $$2 : 3$$. These two charges are kept at a distance $$1 m$$ apart in vacuum. Then, the electric force between them (in N) is:

In winter season, a mild spark is often seen when a man touches somebody else's skin. Why?

The figure shows two situations in which a Gaussian cube is placed in an electric field. The arrows and values indicate the directions and magnitudes (in $$\displaystyle N-{ { m }^{ 2 } }/{ C }$$) of the electric fields.What is the net charge (in the two situations) inside the cube?

In the thunderstorm, the charges accumulate near the upper edges of clouds are

When a comb is rubbed with hair, it attracts paper bits. Choose the right explanation:

Identify which of the above shown graphs represents the force between two electrons Vs distance between them?
