The lines which provide information about the electric force exerted on charged particles are:

The electric field lines are closer where the field is:

The electric field produced due to negative charge is always:

When vector area is held parallel to electric field lines, the the magnitude of electric flux is:

The total electric flux through any close surface is directly proportional to:

Electric flux through a close surface does not depend upon:

The electric intensity is expressed in unit of N/C or

Gravitational force between two objects does not depend upon

In Millikan's experiment, the oil drop can be suspended between two plates when the gravitational force is equal to

A particle having 2e charge falls through a potential difference of 5V. The energy acquired by it is
