Answer:
0.018 N
Explanation:
From the given information;
We understood that A and C possess the same current direction, thus the force between them is said to be an attractive force.
Also, between B and C, there exist different current directions, thus, the force between them is said to be a repulsive force.
So, the force per unit length magnitude are as follows:
Similarly;
Thus, the net force acting on 4.0 - m length of the wire C is:
Thus, the magnitude of the force on a 4.0-m length of wire C = 0.018 N

Answer:
F = 2.49 x 10⁻⁹ N
Explanation:
The electrostatic force between two charged bodies is given by Colomb's Law:
where,
F = Electrostatic Force = ?
k = colomb's constant = 9 x 10⁹ N.m²/C²
q₁ = charge on proton = 1.6 x 10⁻¹⁹ C
q₂ = second charge = 1.4 C
r = distace between charges = 0.9 m
Therefore,
<u>F = 2.49 x 10⁻⁹ N</u>
Answer:
Explanation:
w = mg, and no matter where we go, our masses will never change. Our weight does, however, depending upon the gravity of where we are. Let's first find the weight of the man on earth, where the pull of gravity is -9.8 m/s/s:
w = (60)(-9.8) so
w = 590 N rounded from 588. It's negative because weight is a downward value (whereas Normal force is the upward value of this measurement, making Normal force the positive of this same number)
Now for the moon, where gravity is 1.6 m/s/s:
w = (60)(-1.6) so
w = -96 N
