Question

A 0.578 kg salami is supported by a cord that runs to a spring scale, which is supported by another from the celling (see Figure(a)). What is the reading on the scale, is marked in weight units? (b) In Figure (b) the salami id supported by a cord that runs around a pulley and to scale. The opposite end of the scale is attached by a cord to a wall, What is the reading on the scale?(c) In Figure (c) the wall has been replaced with a second 0.578 kg salami on the left, and the assembly is stationary. What is the reading on the scale now? (a) Number (b) Number (c) Number

Explanation / Answer

a) Tension in the string = mg = 0.578 x 9.8 = 5.6644 N.

b) Again for this setup also 5.6644 N.

c) Since tnesion in both the strings, right and left, is equal, net tension is zero, experienced by the balance. So, reading = 0 N.
