Question

1. two charged spheres q1 = 2.00x10^11 C; and q2=-5.00x^-8C are held fixed at positions 0.0500m apart. Calculate the magnitude of each electrostatic force between two spheres
2. Determine the electric flux of an electric field E = 2000 N/C with an area of 10m^2 and 45 degree angle
3. compute for the amount of charge (q) that passes through a conductor in 10 seconds with the amount of current equal to 20 a.

Answer 1

1.

$F=\frac{kq_1q_2}{r^2}=3.6~\mu N,$

2.

$\Phi=EA\sin\alpha=14~kVm,$

3.

$q=It=200~C.$
