A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle).

Length of the ruler: 1 m

Mass of the ruler: 800 g

Two masses are placed on the ruler. You need to find where to place the third mass to balance it.

Mass 1: 294 g. This mass is placed at the 23-cm mark on the ruler.

Mass 2: 227 g. This mass is placed at the 69 cm mark of the same ruler.

At what mark should a third, 286-g mass be placed to restore the balance?

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
