Question

Electric Charge and Force. The electrostatic force between two charges is 37x 10" The two charges are 01 23 C and Q2 = 79 Calculate the separation between the two charges, in units of meters

Answer 1

Here we have given that,

Force F = 3.7×10^-9 N

Q1 = 2.3 uC

Q2 = 7.9 uC

Now from the coulomb law we have,

F = kQ1Q2/R²

Where k = 8.99×10⁹ Nm²/C²

From here,

R² = Kq1q2/F = 8.99×10⁹×2.3×7.9×10^-12/3.7×10^-9

R² = (44148189.18918919)

R = (6644.41037182301) m

Which is the seperation distance between the charges.
