"A horizontal loop of wire has a magnetic field passing upward through the plane of the loop. If this magnetic field increases with time, is the direction of the induced current clockwise or counterclockwise (viewed from above) as predicted by Lenz's law?

Anticlockwise direction

Explanation:

According to Lenz law, the induced current acts in a direction that opposes the change of flux producing it.

The loop is horizontal, and the magnetic flux is acting upward from the horizontal plane. This means that a Noth pole induced magnet has to be produced to counter this effect.

Anticlockwise flow of induced current produces a Noth seeking magnet while the reverse is true for a clockwise flow.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign.
