AP Physics C E and M

Question

A point charge of +10 μC is at (+3 m, 0 m) on the x-axis and a point charge of +10 μC is at (-3 m, 0 m).

Determine the work required to assemble this charge distribution

Answer 1

Potential energy experienced bringing two point charges 6 m apart is k_eQ₁Q₂/d . This the the work required to put these charges together.. nC are 10^-9 C and k_e is 8.99 x 10⁹ J-m/C²
