Question

the figure shows an electron moving along an electric dipole axis toward its negative side (x-axis). the electron was initially very far from the dipole with kinetic energy = 100eV (y-axis) as shown in the figure. the horizontal scale is set by rs=0.1m. Find the dipole moment. your answer in X.X 10^12 C*m

The figure shows an electron moving along an electri electron was initially very far from the dipole with kir figure). The horizontal scale is set by r,-0.1 m. Find t C.m Solution: screencast CH24 07 lo0 50 r (m) Question 8

Explanation / Answer

We know that, potential energy due to dipole = kp q/r^2

100*1.6e-19 =9e9 *1.6e-19 p/0.02^2

100*0.02^2 /9e9 = p

p = 4.4 *10^-12 Cm answer
