Question

I am unsure about how to solve the attached calculus question.

Part A
The human heart consists largely of elongated muscle
cells, some 100 µm long and 15 um in diameter. In its
resting state, a cell contains two concentric layers of
charge, which confine the electric field to the cell
membrane, as in the first figure. When the heart contracts,
a wave of depolarization sweeps through, depleting
charge and giving each cell a dipole moment, as in the
second figure. As a result, the entire organ acts like an
electric dipole, producing an external field, which is
indirectly detected by electrocardiography. Although the
direction of the heart's dipole moment varies, the third
figure is typical. In answering the questions that follow,
consider the heart in isolation-don't concern yourself with
the effect of surrounding tissues on its electric field.
(Figure 1)
At a distance r, far from the heart, the heart's electric field
falls off as 1/r.
falls off as 1/r2.
falls off as 1/r3.
falls off as 1/r*.
