Answer on Question #47028 – Math – Vector Calculus

Question: a horizontal force $35\,N$ acting to the right would be indicated by a line and if the chosen vector scale were $1\,cm = 10\,N$, how long the line would be?

1) 3.5

2) 3

3) 4.5

4) 2

Solution: the chosen vector scale is

$$1\,cm = 10\,N$$

It means that to a force $1\,N$ corresponds a line that has length $0.1\,cm$.

$$1\,N = \frac{1}{10}\,cm = 0.1\,cm$$

Then a force $35\,N$ acting on a body would be indicated by a line of length

$$L = 0.1 \cdot 35\,cm = 3.5\,cm$$

Answer:

1) $3.5\,cm$
