Question

5) So far in class we have examined the force exerted by a dipole. Now what about the force exerted on a dipole? qc Let's model a dipole as a negative (qA) and a positive (qB) charge linked by a solid bar of length 2L that won't stretch or compress. There is a nearby negative charge (qc) that is a distance d above the midpoint of the bar. Assume all the charges in the picture have the same magnitude of charge, q. 4A Чи A) Start by making a prediction. What do you think will happen to the dipole because of the force exerted by the negative charge? Will it move? If so, how? B) Using the numbers to the right, determine the magnitude FcA of the Coulomb force that qc exerts on qA A 10 nC B- 10 nC c 10 nc L- 300 um d 400 μ m C) Sketch the vector Fca. Use your drawing to determine its x- and y-components Ic Чл CA,Y D) Determine the magnitude Fp of the Coulomb force that ac exerts on gR.

I know it's a long question but if you could answer all parts of it that'd be awesome!!

Answer 1

a) The dipole will move towards left because a net force(electroctstatic) due to negative charge will be produced towards left.

b)
