A point-like charge + is separated by a distance d = 40 cm from a uniform planar distri- bution with charge density o = 8.86-10-10 5. An electric dipole of magnitude pl = 10-12 C-m is located at a distance from the point-like source. The dipole is oriented parallel to the 1-axis, i.e. þ= F. 1. On the dipole, a force of magnitude F = 2.25 - 10-N is exerted along the r-direction. 1 b ++++ + B p tet A х d/4 d/2 ++++ d 1. Calculate 4, making use of the equation found above for the force acting on a dipole. Hint: How many dimensions do we need to take into account in order to solve this problem? Hint: Are both the charged wall and the charge contributing to the force on a dipole? 2. Calculate the velocity Ug an electron (me=0.9. 10-50 kg, qe = 1.6.10-19 C) will have in point B if it leaves from point A with = -3.10.
