Question
A ________ charge shows the direction of electric force at a point due to a charged body.
- Neutral
- Test
- Unit
- Negative
Hint:
Test charge
The correct answer is: Test
- A test charge shows the direction of electric force at a point due to a charged body.
- So, the correct answer is test.
- 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.
