Asolid conducting sphere is placed in an external uniform electric field. with regard to the electric field on the sphere's interior, which statement is correct? a solid conducting sphere is placed in an external uniform electric field. with regard to the electric field on the sphere's interior, which statement is correct? the interior field points in a direction perpendicular to the exterior field. the interior field points in a direction opposite to the exterior field. there is no electric field on the interior of the conducting sphere. the interior field points in a direction parallel to the exterior field.

There is no electric field on the interior of the conducting sphere.

Explanation:

When conducting sphere is placed in external electric field then as we know that all conductors will have large amount of free charge present inside the conductor, this free charge will experience force due to this external electric field and start rearrange itself.

This rearrangement of charge is known as induction in conductors

This rearrangement will continue takes place till the electric field due to this rearrangement of charge will counterbalance the external electric field.

So at the steady state position the net electric field inside all conductors must be zero

so here correct answer would be

There is no electric field on the interior of the conducting sphere.

f=ma newton

f=100x2.5=250n

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
