Question

A point charge is brought in an electric field. The electric field at a nearly point :

• A. will increase if the charge is positive
• B. will decrease if the charge is negative
• C. may increase if the charge is positive
• D. may decrease if the charge is negative

Answer 1

Answer: (C), (D)

may increase if the charge is positive
may decrease if the charge is negative

The electric field is proportional to the charge i.e $E=kq/r^2$. So positive charge may increase the field and negative charge may decrease the field.
Ans: (C),(D)
