JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

Two point charges

+ 3\mu C

and

+ 8\mu C

repel each other with a force of 40

N

. If a charge of

- 5\mu C

is added to each of them, then the force between them will become

View answer and explanation

Correct option: B

+ 10N

Option B (

+ 10N

) is correct because the force is proportional to the product of the charges, and adding the same charge to both changes the magnitude and sign of the force.

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
