Answer:
5.619×10⁶ N
Explanation:
Applying,
F = kqq'/r²................... Equation 1
Where F = electrostatic force between the charges, k = coulomb's constant, q = first charge, q' = second charge, r = distance btween the charges
From the questiion,
Given: q = 2.5 C, q' = 2.5 C, r = 100 m
Constant: 8.99×10⁹ Nm²/C²
Substitute these values into equation 1
F = (2.5×2.5×8.99×10⁹)/100²
F = 56.19×10⁵
F = 5.619×10⁶ N
The answer is True since thats what usually goes on
Energy is transfered when its moved from one object to another. The rate of energy transfered is called power. Work is the transfer of energy from one object to another.

Answer:
I = 33.04A
Explanation:
The magnetic field at the center of a loop of wire is proportional to the current flowing through the wire and inversely proportional to the radius
So therefore we have:
20/23 = I/38.0
We then solve for I
cross multiplying we have 20 x 38 = 23 x I
I = 20 x 38/ 23
I = 33.04A
