Question

A force of 150 N can
loosen
a nut when
applied at the end of a
spanner 10 cm long.
1. What should be the
length of the spanner
to loosen the same
nut with a 60 N force?
2. How much
force
would be sufficient to
loosen it with a 6 cm
long spanner?​

Answer 1

Answer:

250N

Explanation:

$f \times d = f \times d \\ 150 \times 0.1 = f \times 0.06 \\ 15 = f0.06 \\ \frac{15}{0.06} = f \\ 250n = f$
