Question
A test charge is always taken ________ and ____________.
- Small, positive
- Large, positive
- Small, negative
- Large, negative
Hint:
A test charge is always taken inorder to study the effects of another charges or field in the vicinity.
The correct answer is: Small, positive
A test charge is always taken inorder to study the effects of another charges or field in the vicinity. It is taken to be a point charge so that its dimensions are small and its magnitude is small enough so that it does not create its own stong field and interact with the field to be tested
