Hanging Scale
A brick is 2 kg weight in H20, spring scale reads 14.0 N, the upward force of H20 in the brick?
A brick of mass is 2.00 kg "Heavy under water" with her hanging on a dynamometer. (A) If the spring scale reads 14.0 N, what is the upward force water over the brick? (B) What is the reading level of the pot that is the recipient? The weight of water and container and is 12.0 N.
The weight of the bricks out of the water would be: 2 kg * 9.8 m / s / s or 19.6 newtons. Since it weighs only 14.0 newtons, water must exert upward force of 5.6 Newtons. From the glass exerts upward force on the brick 5.6 newtons, the brick must exert a downward force to 5.6 newtons. Add to that the weight of water and container and you get 17.6 newtons. If the pot is calibrated scale reading in kilograms, you must read 17.6/9.8 kg.
