How does doubling each of the following quantities affect the force between a dipole and a particle placed near the dipole and carrying charge \(q\) :

(a) the charge \(q,\) 

(b) the dipole separation \(d\) of the dipole, 

(c) the dipole charge \(q_{\mathrm{p}}\),

(d) the distance between the dipole and the charged particle?
