Chapter 21, Problem 62P

SSM In Fig. 21-44, what are the (a) magnitude and (b) direction of the net electrostatic force on particle 4 due to the other three particles? All four particles are fixed in the xy plane, and q₁ = −3.20 × 10⁻¹⁹ C, q₂ = +3.20 × 10⁻¹⁹ C, q₃ = +6.40 × 10⁻¹⁹ C, q₄ = +3.20 × 10⁻¹⁹ C, θ₁ = 35.0°, d₁ = 3.00 cm, and d₂ = d₃ = 2.00 cm.
