Question

Two charges +6microcoloumb and -2microcoloumb are separeted by a distance of 30cm in air. Find the electrostatic force between the charges

Answer 1

Answer:

1.2 N

Explanation:

Electrostatic force,

F = k q1 q2 / r^2

F = (9*10^9) * (6*10^-6) * (-2*10^-6)

( 30*10^-2) * (30*10^-2)

F = - 1.2 N

( - ve sign is indicating that force is attractive type)
