Answer:
Th steps is as shown in the attachment
Explanation:
from the diagram, its indicates that twelve identical charges are distributed evenly on the circumference of the circle. assuming one of gthe charge is shifted to the centre of he circle alomng the x axis, as such the charge is unbalanced and there is need ot balanced all the identical charges for the net force to be equal to zero.
The mathematical interpretation is as shown in the attachment.
The net force (magnitude and direction) of the system given in the question is 40 N horizontal to the right
<h3>How to determine the net force</h3>
Case 1 (Net force between up and downward force)
- Force up (Fu) = 50 N
- Force down (Fd) = 30 N
- Net force 1 (F1) = ?
F1 = Fu - Fd
F1 = 50 - 30
F1 = 20 N up
Case 2 (Net force between right and left)
- Force right (Fr) = 60 N
- Force left (Fl) = 20 N
- Net force 2 (F2) = ?
F2 = Fr - Fl
F2 = 60 - 20
F2 = 40 N right
SUMMARY
- Net force between up and down = 20 N up
- Net force between right and left = 40 N right
From the above, the net force between right and left (i.e 40 N) is greater than the net force between up and down (i.e 20 N)
Thus, the net force of the system will be 40 N horizontal to the right

A control variable is the one element that is not changed throughout an experiment.A dependent variable is a variable whose variation does not depend on that of another.A independent variable is a variable whose value depends on that of another.
Answer:
4 %
Explanation:
mass of the object 1, m₁ = 0.1 Kg
initial velocity of object 1,v₁= 0.2 m/s
mass of object 2, m₂ = 0.15 kg
initial speed of the object 2. v₂ = 0 m/s
Kinetic energy retained by the object 1 = ?
using the formula to calculate velocity of the ball after collision
negative sign represent the velocity is in opposite direction after collision.
Initial KE
final KE
% of KE retained
=
=
= 4 %
the percentage of Kinetic energy retained after collision is equal to 4 %
