As shown in the figure(Figure 1), five balls (masses 2.00,
2.05, 2.10, 2.15, 2.20 kg) hang from a crossbar. Each
mass is supported by "5-lb test" fishing line which will
break when its tension force exceeds 22.2 N (= 5 lb).
When this device is placed in an elevator, which
accelerates upward, only the lines attached to the 2.10.

Expert Answer

Step 1

Given data:

Minimum tension, Tmin = 22.2 N

Masses:

Physics homework question answer, step 1, image 1

Step 2

From the Newton’s second law, the net force on a mass in a lift which is moving upward can be written:Physics homework question answer, step 2, image 1

Step 3

For the minimum acceleration, it is necessary to break off  heaviest mass, therefore:
