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 _____.

An electron generally exists ______ the _________of an atom.

What is the nature of electrical charges generated by rubbing two objects?

An electron has __________ charge.

 

Negative charge attracts ________ charge.

 

Consider the following statements and select the correct option which correctly identifies true (T) and false (F).
(i)A charged object can attract something that is uncharged.
(ii) An atom that gains electrons becomes positively charged.
(iii) Charges can be transferred from one body to another.
