Answer 1

So, the correct answer is option b) 0.3 N.

Step-by-step explanation:

Let's analyze the given information step by step to determine the weight of one disc.

The reading on the spring balance with a holder and eight identical discs is 3.0 N.

Six discs are removed, and the reading becomes 1.2 N.

To find the weight of one disc, we need to calculate the weight of the six discs that were removed.

The difference between the initial reading (3.0 N) and the reading after removing six discs (1.2 N) gives us the weight of the six discs. Therefore:

Weight of six discs = 3.0 N - 1.2 N = 1.8 N

Since there were six identical discs, the weight of one disc can be calculated by dividing the weight of six discs by 6:

Weight of one disc = 1.8 N / 6 = 0.3 N

Therefore, the weight of one disc is 0.3 N.

So, the correct answer is option b) 0.3 N.
