Question
A test charge may be of any magnitude.
- True
- False
Hint:
A test charge is a vanishingly small positive charge that is used to detect the presence of an electric field
The correct answer is 'False'.
A test charge is a vanishingly small positive charge that is used to detect the presence of an electric field. The test charge should be as small as possible so that its presence does not affect the electric field due to the source charge. The electric charge that produces the electric field is called a source charge.
