Topic: charge and electric field Please answer the question in the photo b. Consider the following incorrect statements made by three students regarding this situation Student 1: The test charge is negative, so it will reduce the electric field where it is Student 2: "I disagree. The test charge is negative, so it will flip the direction of the Student 3: "When the test charge is at point A, it contributes to the field at points B and C Explain why each student is incorrect. (Hint: What assumptions are made about test placed. electric field, but it won't change the magnitude." but not at point A. Test charges don't affect the field where they are." charges?)Explanation / Answer
The electric field is a vector field; it consists of a distribution of vectors,one for each point in the region around a charged object. In principle, we can define the electric field at some point near the charged object.
as test charge has its own field, so when the test charge is introduced in the field of concerned charged object, say another point charge +q , won't it get shifted due to the repulsion from the test charge q0 Then consequently the field of +q will also be shifted.
