Question

the force between two similar charges of magnitude 2 c each separated by a distance 2km

Answer 1

as they are similar charges .the force is repulsive force .

Answer 2

Answer:

Electrostatic force, F = 9000 N

Explanation:

Charge, q₁ =2 C

Charge q₂ = 2 c

Distance between charges, d = 2 km = 2 × 10³ m

We have to find between two charges. It can be calculated as :

$F=k\dfrac{q_1q_2}{d^2}$

k = electrostatic constant

$F=9\times 10^9\times \dfrac{2^2}{(2\times 10^3)^2}$

F = 9000 N

Hence, the electrostatic force acting between two charges are 9000 N.
