Question

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

Part A
Youd're 1.44 m from a charge distribution that is well
under 1 cm in size. You measure an electric field
strength of 296 N/C due to this distribution. You then
move to a distance of 2.16 m from the distribution, where
you measure a field strength of 87.7 N/C.
Determine instead how the field decreases with distance.
O Field falls off like r 2 for r> a, so the charge distribution must be a monopole.
O Field falls off like r 2 for r> a, so the charge distribution must be a dipole.
O Field falls off like r
3 for r>a, so the charge distribution must be a dipole.
O Field falls off like r
for r>a, so the charge distribution must be a monopole.
