Question

a uniform metre scale can be balanced at 70 cm mark when the mass 0.05 kg is hung from the 94 cm .Draw the diagram of the arrangement. Find the mass of the metre scale​

Answer 1

Thus the mass of the meter scale is 60 g.

Explanation:

We are given that:

• Mass of object = 0.05 Kg
• Balancing distance = 70 cm
• Distance from hanging point = 94 cm

Solution:

According to the  principle of moments

m1 x1 = m2 x2

m1 x (70 - 50) = 0.05 x (94 - 70)

m1  = 0.05 x 24 / 20  

= 0.06 kg

To convert it into grams multiply by 1000.

= 0.06 x 1000 = 60 g

Thus the mass of the meter scale is 60 g.

Answer 2

Answer:

m1 x1 = m2 x2

m1 x (70 - 50) = 0.05 x (94 - 70)

m1  = 0.05 x 24 / 20  

= 0.06 kg

To convert it into grams multiply by 1000.

= 0.06 x 1000 = 60 g

Thus the mass of the meter scale is 60 g.
