Question

Determine the angle of the net electric field at the origin. Use the +Y axis as your reference direction and move counter clockwise. Give your answer to the nearest degree in the form "bc.d" degrees. Two hypothetical point particles, particle A, comprised of 15 electrons and a proton and the particle B comprised of 15 protons and an electron are separated by a distance of 16.8 nm to form an electric dipole. The dipole moment vector has magnitude C.m and points from particle _____ to particle _____. Choose the correct answer below. Give your answer in the form "X" whore X is the letter corresponding to the correct answer choice below. Answer choices: 4.03 times 10^(-26), A, B. 4.03 times 10^(-26), B, A. 3.76 times 10^(-26), B, A. 3.76 times 10^(-26), A, B.

Explanation / Answer

Particle A has a charge of 15e- + e+ = 14*e- = -14*1.6*10^-19 = -22.4*10^-19 C

Particle B has a charge of 15e+ + e- = 14*e+ = 14*1.6*10^-19C = 22.4*10^-19 C

length of the dipole is l = 16.8*10^-9 m

then dipole moment is p = q*l = 22.4*10^-19*16.8*10^-9 = 3.7632*10^-26 C-m

direction is from negative charge to positive charge

so answer is from A to B

final answer is D) 3.76*10^-26 C-m from A to B
