Answer 1

Answer #1

The electric force between any 2 point charges q1 and q2 at a distance r is given by

EF=kq1q2/(r²)

Where, k= Coulomb constant= 8.99x10⁹ N-m² / C²

And given that, q1=q2= 4x10^-6 C and r=0.04 m

Therefore, putting these values in above formula

EF = (8.99x10⁹ x 4 x 4 x 10^-12)/(0.04x0.04)

= 89.9 N
