19522.	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 : (A) Both statement-I and statement-II are true. (B) Both statement-I and statement-I are false. (C) Statement-I is true but statement-II is false. (D) Statement-I is false but statement-II is true.
Answer» (C) Statement-I is true but statement-II is false. 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.

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 : (A) Both statement-I and statement-II are true.

Answer»

(C) Statement-I is true but statement-II is false.

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.

Answer»

(a) √2 and angle 45°

IN with angle 45 degrees with x-axis

Net force in x- direction = -IN

Net force in y-direction = -IN

∴ Force required to balance = 1 \(\hat{i}\) +1 \(\hat{j}\)

∴ Angle it makes is 45° with x-axis
