- MCQ
Given below are two statements Statement \(-I\) : A point charge is brought in an electric field. The value of electric field at a point near to the charge may increase if the charge is positive. Statement \(-II\) : An electric dipole is placed in a non-uniform electric field. The net electric force on the dipole will not be zero. Choose the correct answer from the options given below
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) Statement \(-I\) is true but statement \(-I\) is false.
Step-by-step Solution
Detailed explanation
If the electric field is in the positive direction and the positive charge is to the left of that point then the electric field will increase. But to the left of the positive charge the electric field would decrease.
If the dipole is kept at the point where the electric field is maximum then the force on it will be zero.
