Solution

Weight $= M a s s \times a c c e l e r a t i o n$
Acceleration due to gravity on the earth's surface:
Weight $= m g$
$49 N = 5 \times g$
g = 9.8 m/s $^{2}$
Acceleration on the moon:
$\frac{1}{6} \times 9.8 = 1.6333 m / s^{2}$
The weight on the moon:
5 $\times$ 1.6333= 8.1665 N
Answer: 8.1665 N
