The electric force acting between two charges doesn’t depend upon:

Which of the given physical quantities is/are vector? Choose the most suitable option.

The unit of the charge is_________.

• The SI unit of length is meter.
• The SI unit of force is Newton.

The electric force acting between two charges depends upon:

If a charged sphere is exerting a force of 8N on a charge of 4C at a point, then find the electric field strength at that point.

A test charge may be of any magnitude.

The S.I. unit of electric field strength is __________.

A test charge is always taken ________ and ____________.

A ________ charge shows the direction of electric force at a point due to a charged body.

• A test charge is a charge with a magnitude so small that placing it at a point has a negligible affect on the field around the point.
• A positive test charge is a unit positive charge which is used to determine the strength and direction of an electric field.

The electric force ___________ on the medium between the charges.

• K= 1/4πε
• The value of k depends on the electric permittivity of the medium (ε).
• And the electric permittivity of a medium (ε) depends on the nature of the medium.
• Therefore, the value of K is different for different medium.
• Hence, the electrostatic force depends on the medium between the two charges.

If an object is rubbed with another object, the object which loses electrons:

Two charged objects are brought into close proximity. Select the most appropriate statement from the options given.

The process of rubbing results in a transfer of _________ from one body to the other.

Like charges ______.

“A positive charge attracts a positive charge.” this statement is ____.

"Charges always attract other charges." This statement is _____.
