I need help with my physics, they’re just tick boxes
The magnet was placed on the top pan balance before the current was switched on. The balance then was zeroed. After the current was switched on the balance read 161g. The arrow shows the direction of the current in the circuit
Which direction was the force on the balance?
Choose one
1. In the same direction as the arrow (in the image)
2.down into the balance
3.up from the balance
4from the front of the balance to the back of the balance
Due to Newton‘s third law of motion, the force on the wire is in the opposite direction to the force on the balance which direction was the magnetic field. Choose one
1.in the sand direction as the arrow in the image
2.down into the balance
3. Up from the balance
4. From the front to the back of the balance

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
