Physics- Coulomb's Law
posted by Kristal .
1) Particles of charge Q1 = +77 µC, Q2 = +44 µC, and Q3 = -80 µC are placed in a line. The center one (Q2) is 0.35 m from each of the others. Calculate the net force on Q1 and Q2 due to the other charges.
a) Force on Q1
b) Force on Q2
2) A charge of 3.9 nC and a charge of 5.9 nC are separated by 7 m. Find the equilibrium position for a -4.2 nC charge.
