Why not all letters of the alphabet are used in loading coil distance?
and why there is no pattern followed in the spacing designation?thank you very much...
a)the forces between q1 and q3
F = k * (q1 * q3/d13^2)
k = (1/4πεo) = 9 * 10^9 Nm^2/C^2 and d13= 20 cm = 20 * 10^-2 m
F=-1.125N
b)the force between charges q1 and q3 is
F1 = k * (q1 * q3/d13^2)
= -1.125N
the force between charges q1 and q2 is
F2 = k * (q1 * q2/d12^2)
=3.5N
