Question

In reality, the magnitude of the force between the two spherically symmetrical charge distributions is described by Coulomb’s law

F= (kq1q2)/d^2

where k is a constant equal to 8.99×10⁹ Nm2/C2, q1 and q2 are the magnitudes of the charges, and d is the distance between the centers of the spheres.

Assuming that both spheres have equal charges, estimate the charge on each sphere, using the first data point in your table. Remember that, for the calculations to be correct, both force and distance must be expressed in their respective SI units.

Note that 1nC=10^−9C.

The first suggested data point was 31.9 cm and 0.00016 N.
