Question

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

Answer 1

4.2 x 10⁷N

Step-by-step 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 =
`(k q_(1) q_(2) )/(r^(2) )`

where k = 9 x 10⁹Nm²/C²

q is the charges

r is the distance

Input the variables and solve;

F =
`(9 x 10^(9) x 3 x 14 )/(9000)` = 4.2 x 10⁷N
