Question 1134107
{{{ F = k((q[1]*q[2])/r^2) }}}
<br>
where {{{ k = (8.98755x10^9) (N*m^2/C^2) }}}<br>

A. {{{ F = (((8.98755x10^9)(25x10^-9)(-75x10^-9)) / (0.03)^2 )  = -0.01872N}}}

(minus sign ==> force is toward each other, also note opposite charges attract,
like charges repel)<br>

B. Same as A.
