Asolid nonconducting sphere of radius r carries a charge q distributed uniformly throughout its volume. at a certain distance r1 (r1 < r) from the center of the sphere, the electric field has magnitude e. if the same charge q were distributed uniformly throughout a sphere of radius 2r, the magnitude of the electric field at the same distance r1 from the center would be equal to:

Explanation:

As we know that that electric field inside the solid non conducting sphere is given as

so electric field is given as

now if another sphere has same charge but twice of radius then the electric field at same position is given as

so here we have

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !
