(1)
according to the law of gauss and superposition Law:
; electric field due to the small sphere with r1=R/4
then: (2)
on the other hand, for the particule:
⇒
(3)
We replace (2) y (3) in (1):

if R<x<2R AND
remember that
then:
solving:
but: R<x<2R
so :
Answer:
The reason is because both are exposed to a virtually infinite heat sink, due to the virtually infinite mass and of the surrounding environment, compared to the sizes of either the cup or the kettle such that the equilibrium temperature, reached is the same for both the cup and the kettle as given by the relation;
Due to the large heat sink, T₂ - T₁ ≈ 0 such that the temperature of the kettle and that of the cup will both cool to the temperature of the environment

Answer with Explanation:
We are given that
a.We have to find the total dose
Total dose=
Using the formula then, we get
b.We have to find the total dose equivalent
Total dose equivalent=H=
Using the formula
H=3.1mSv
