Answer:
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
Sum the forces in the y (upward) direction
Applying the kinematic equations of linear motion we have that the displacement as a function of the initial speed, acceleration and time is
Again through the kinematic equation of linear motion that describes velocity as the change of displacement in a given time, we have to
Therefore the horizontal distance between the target and the rocket should be 38.83m
