JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Analyzing +4 | -1

Assertion: Two charges

{q}_1

and

{q}_2

are placed at separation

r

. Then magnitude of force on each charge is

F

.

Reason: Now a third charge

{q}_3

is placed near

{q}_1

and

{q}_2

Then force on

{q}_1

due to

{q}_2

remains

{F}

View answer and explanation

Correct option: B

Both Assertion & Reason are true. Reason is not the correct explanation for assertion

Option B (Both Assertion & Reason are true. Reason is not the correct explanation for assertion) is correct because the force between two charges is independent of the presence of other charges, although the net force on a charge will be affected.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance
