PLEASE PLEASE PLEASE A mad scientist places massive amounts of charge on basketball sized aluminum balls. The charge on the balls are 3 C on one ball and 14 C on the another. The balls are moved to a distance of 9000 m apart. What magnitude of force will act on the two balls?

N

4.2 x 10⁷N

Explanation:

Given parameters:

Charge on ball:

             q₁  = 3C

              q₂ = 14C

Distance between balls  = 9000m

Unknown:

Force acting on the two balls

Solution:

The force experienced by the two charges is given by coulombs law. It is mathematically expressed as;

                      F  =

where k  = 9 x 10⁹Nm²/C²

           q is the charges

             r is the distance

Input the variables and solve;

        F  =  = 4.2 x 10⁷N

explanation:

v=uf/(u-f)
