Consider two point charges 91 = 6nC and 92 = 4nC positioned at x = (51 - 79k)cm and x2 = (2 + 3 7)cm, respectively. = (a) Express the electrostatic force acting on particle 1 in the form F1 F() + F() } + F() k and the electrostatic force on particle 2 in the form F2 = (F() + F() + F) ) with numerical values for all six components in SI units. (b) Relocate particle 1 to the position x = (x y + z ) such that it experiences the force F = (5 + 7 +8) 106N. Find the three coordinates x1, 31, in units of cm.
