JEE PHYSICS MCQ: ELECTRIC FIELDS AND CHARGES

1 Medium

1 of 1

Application +4 | -1

Two concentric conducting thin shells of radius

r

and

2 r

carry charges

+2 q

and

+6 q

, respectively. The magnitude of electric field at a distance

x

outside and inside from the surface of outer sphere is same, then the volume of

x

is

View answer and explanation

Correct option: B

\frac{2 r}{3}

Option B (

\frac{2 r}{3}

) is correct because it represents the distance x where the electric fields due to the charged shells are equal outside and inside the outer sphere.

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
