Which of the balls will exert the smallest force on object A?Why
olganol [36]
The 1kg ball would exert the smallest force.

As force = mass x gravity, this means that the smaller the mass (kg), the lesser the force.

When the mass is lighter (1kg):

Force = mass x gravity
Force = 1 x 9.8
Force = 9.8N

Compared to when the mass is heavier (10kg)

Force = mass x gravity
Force = 10 x 9.8
Force = 98N

Where this proves that the lighter the mass, the smaller the force exerted.

At which angle do wires have to be to experience full force? What happens at other angles?
lisov135 [29]

Answer:

The angle wires have to be placed to experience full force is such that the angle between the direction of current flow and the direction of the magnetic field is 90°

Explanation:

The direction of the force acting on a conductor through which a charge flows  is given by Flemings Left Hand Rule which states that the direction of the force acting on a conductor carrying a current of charge is perpendicular to both the direction in which the current is flowing and the direction of the magnetic field

Therefore, wires carrying flowing charges has to be placed such that the direction of charge (current) flow is perpendicular (at 90°) to an existing magnetic field to experience (maximum) full force
