Question

The table below represents the data found by dragging solid brass weights across a desk with a spring scale. If the acceleration due to gravity is 9.81 m/s², what mass would experience a frictional force of 2 N?

| Normal Force (N) | Frictional Force (N) |
|------------------|----------------------|
| 1.5 | 0.4 |
| 4.1 | 1.0 |

Options:
a) 0.54 kg
b) 0.86 kg
c) 4.0 kg
d) 8.3 kg

Expert Solution

Step 1

Friction Force (f)= $μ N$

where, $μ = friction coefficent$

$N = Normal Force$

based on the given Table , we can calculate $μ$

(i) f=0.4 N and N=1.5 N , $μ_{1} = \frac{f}{N} = \frac{0.4}{1.5} = \frac{4}{15}$

(ii)f=1.0 N and N=4.1 N , $μ_{2} = \frac{f}{N} = \frac{1.0}{4.1} = \frac{10}{41}$
